The height assumption first, because a square-footage question cannot be answered without one. I am taking 12 feet for the main floor, which sits in the middle of the ordinary boutique range of 10 to 14, and I will show the alternatives because at this size they matter enormously. 2,500 sq ft at 12 ft is 2,500 x 12 = 30,000 cubic feet, and 30,000 divided by 35.3 is about 850 cubic metres. At 14 ft it is 35,000 cubic feet, about 991 cubic metres. At a low 10 ft, 25,000 cubic feet, about 708. And at a mall-flagship 16 ft, 40,000 cubic feet, about 1,133 cubic metres - which is the first number in this whole section that exceeds the approximately 1000 cubic metres of connected air a SOSA Vaayu at ₹11,999 is rated for, and it is worth saying so plainly rather than selling around it.
Now the correction that changes everything. A 2,500 sq ft multi-brand store is hardly ever one connected body of air. It is usually four or five. A very ordinary plan: 1,400 sq ft of main floor, a 300 sq ft brand room with a door, a 350 sq ft collector lounge, a 150 sq ft private viewing room, and 300 sq ft of back of house. Compute them: the main floor at 12 ft is 1,400 x 12 = 16,800 cubic feet, about 476 cubic metres; the brand room at 12 ft is 3,600 cubic feet, about 102; the lounge at 11 ft is 3,850 cubic feet, about 109; the viewing room at 10 ft is 1,500 cubic feet, about 42; the back of house is 3,000 cubic feet, about 85, and it gets nothing at all.
So the real brief is four volumes totalling about 729 cubic metres of customer air, of which the largest is 476 - under half a Vaayu's rating. Every one of those rooms sits comfortably inside the range of what SOSA sells. The machine is not your constraint. The setting is, and the plan is.
And the thing you may have come here to ask about - a different scent for each brand area - is the one idea this page argues against, for reasons that are partly physical and partly about whose identity it is.
Should each brand area have its own fragrance? No, on two grounds. Physically, brand corners on an open floor are not separate volumes - there is no door between them, so the registers mix in the aisle and produce a third smell that nobody chose and nobody can control. And in terms of identity, the house register is the one thing in a multi-brand store that belongs to the retailer rather than to a supplier; putting a scent character onto an individual maison's corner attaches an olfactory identity to a brand you do not own and do not represent in that way. SOSA is an independent Indian fragrance house and is not affiliated with, endorsed by or connected to any watch manufacturer.
Can one machine do 2,500 sq ft? One machine per connected volume, not one machine per store. If the whole 2,500 sq ft genuinely is one open floor, then at 12 ft you have about 850 cubic metres and at 14 ft about 991, against a Vaayu rating of approximately 1000 cubic metres of connected air - so a single unit is at or near full stretch, and a 16 ft ceiling at about 1,133 cubic metres is past it. More usually the store is four smaller volumes, each well inside range, which is cheaper and more controllable. Two sources on one connected floor is fine, as long as they run the same register at the same level: that is one zone with two sources, not two zones.
So take the plan and mark two things on every space: how long a human being stays in it, and whether the door between it and the next space stays shut. Not square feet, and certainly not which brand is displayed there. Minutes and doors. On the ordinary 2,500 sq ft plan I described above, that gives you four customer volumes and one excluded one:
Main floor, 1,400 sq ft at 12 ft. 1,400 x 12 = 16,800 cubic feet, about 476 cubic metres. Dwell here ranges from four minutes for somebody sheltering from the rain to ninety for a serious appointment, and the level is set by the long tail rather than the average. This is the highest position on the ladder, and even it is low.
Brand room with a door, 300 sq ft at 12 ft. 3,600 cubic feet, about 102 cubic metres. A real zone, because it has a real boundary. Same register, one step down.
Collector lounge, 350 sq ft at 11 ft. 3,850 cubic feet, about 109 cubic metres. The longest dwell in the building - four people, a whole evening, a closed door - and usually the softest room in it. Rugs and upholstery are reservoirs that hold what they are given and release it slowly, so a lounge accumulates where a hard floor does not. Same register, at or below the brand room.
Private viewing room, 150 sq ft at 10 ft. 1,500 cubic feet, about 42 cubic metres - about a ninth of the main floor, holding two or three people for an hour behind a shut door. The lowest level in the building, and the correction that this whole bank keeps having to make: a private room takes a lower setting than the floor, never a deeper one.
Back of house, 300 sq ft. About 85 cubic metres, and it gets nothing. The watchmaker's bench, stock storage, the safe and the office are working rooms rather than customer rooms; the people in them are there eight hours at close range; and ordinary retail prudence keeps a scenting unit away from a bench, open display trays and stock in any case. That is prudence about where a device goes and carries no claim of any kind about fragrance and watches, movements, dials, straps, cases or stock, in either direction.
Four customer volumes, about 729 cubic metres between them, one register, four levels. Not four registers. Two registers either side of a door produce a seam that a client meets every time it opens, and in a multi-brand store where clients move between areas all day, that seam is met constantly. It is the single most reliable way to make an expensive store feel assembled rather than designed.
Which brings us to the idea this page exists to argue against: a different fragrance for each brand area on the open floor. It is a natural thought in multi-brand retail, where every other layer of the store - the casework, the lighting, the signage, the display language - is already zoned by supplier. It does not work, for a physical reason and an identity reason, and both are set out below. A portion of every SOSA order supports girl-child education through Nanhi Kali.
The sentence I would most like a multi-brand owner to take away is this: your register is the only thing in the store that is yours. Every case, every plinth, every piece of signage and most of the lighting in a multi-brand boutique arrives with somebody else's identity attached to it, and the retailer's own identity has to be assembled from what is left - the architecture, the service, the seating, the light in the aisles and the air. Of those, the air is the only one that is present everywhere at once and belongs to nobody but you.
That has a direct consequence for what the register should be like. It has to be neutral enough not to argue with anything. A characterful register - sweet, floral, theatrical, strongly signed - becomes a third voice in a room that already has several, and it is a voice attached to a brand that did not choose it. A quiet, dry, unsigned register does the opposite: it reads as the building rather than as a statement, and it is the same for every maison on the floor, which is exactly the neutrality a multi-brand retailer needs.
The second thing to internalise is that a big store makes your own nose completely useless. You move between four volumes at four levels all day, and adaptation sets in within minutes in each of them. By the afternoon you cannot judge any room in your own building. The two reliable readings are the Monday-morning one - the first appointment of the week, arriving with a clean nose into a store shut since Saturday evening - and your staff, who stand in that air eight to ten hours a day at closer range than any customer. A staff report about the scent is a recalibration signal, not a tolerance problem: turn it down first, discuss it second.
Third, the standing arrangement. A client who says they react to fragrance gets the unit switched off for their appointment by whoever is on the floor, without anybody having to find a manager. In a store with four units, that means everybody knows where all four switches are, and it is written down rather than remembered. No health or allergy claim is made in either direction by having the arrangement; it is simply how a serious store hosts people.
And fourth, the discipline that keeps a four-volume plan intact. The register and the number on a card taped to each machine. One named person who owns the levels. And a rule that nothing gets added to the plan without redrawing the plan - no plug-in on a back shelf, no candle at a desk, no second register in the lounge because somebody liked it. A 2,500 sq ft store has a great many shelves and a great many well-intentioned people.
What a zone actually is in a 2,500 sq ft store, and why it is never a brand corner
Multi-brand retail at 2,500 sq ft has a particular character: it is one business presenting several identities, and almost every design decision is a negotiation between what the store is and what the brands are. Scent is the one layer where that negotiation should not happen at all, and understanding why is most of this page.
Begin with the physical facts, because they settle more than the aesthetic argument does. A coverage rating of any kind assumes one connected body of air. A machine cannot push scent through a closed door, and it has no appetite for pushing it against a pressure difference either. So a building is scented volume by volume rather than floor by floor, and the boundaries between volumes are architectural rather than commercial. A brand corner on an open floor shares its air completely with the corner opposite; a 300 sq ft room with a door shares nothing until the door opens.
Then the arithmetic, done by hand as always. Area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres. At 12 ft the whole 2,500 sq ft is 30,000 cubic feet or about 850 cubic metres, at 14 ft 35,000 cubic feet or about 991, at 10 ft 25,000 cubic feet or about 708, and at a flagship 16 ft 40,000 cubic feet or about 1,133. The compartmented version of the same store is four customer volumes of roughly 476, 102, 109 and 42 cubic metres - about 729 in total, with about 85 cubic metres of back of house excluded entirely.
Then the geometry, because at this size distance is real. A 50 ft by 50 ft floor plate has a corner-to-corner diagonal of the square root of 2,500 plus 2,500, the square root of 5,000, about 71 feet. A 40 ft by 62 ft plate is longer still on its long axis. One point source on a floor that size will always produce a gradient, and the honest response is placement and acceptance rather than a higher setting - or, where the floor genuinely needs it, two sources running the same register at the same level, which is one zone with two sources and not two zones.
And then the identity question, which is where multi-brand differs from every other kind of watch retail and where the strongest temptation lies. The three factors below take these in order: the volumes and their arithmetic; what a zone is and why a brand corner is not one; and the house register, its neutrality, and the limits of what any of it claims to do.
One thing to state before the detail, because it appears on every page in this bank where brand identity comes up. SOSA is an independent Indian fragrance house and is not affiliated with, endorsed by or connected to any watch manufacturer. Nothing SOSA sells represents, evokes or is licensed by any maison, and no page here will suggest that a register belongs to or suits a particular brand.
The lease version. At my assumed 12 ft, 2,500 x 12 = 30,000 cubic feet, and 30,000 divided by 35.3 is about 850 cubic metres. At 10 ft, 25,000 cubic feet, about 708. At 14 ft, 35,000 cubic feet, about 991. At 16 ft, 40,000 cubic feet, about 1,133. Note what happens at the top of that range: the Vaayu is rated for approximately 1000 cubic metres of connected air, so a genuinely open 2,500 sq ft floor under a 16 ft ceiling is past a single machine's rating, and a 14 ft one at about 991 is at it. That is the first point in this whole section where the honest answer is a conversation rather than a product, and it is worth having with your own numbers rather than these.
The reality version. Most 2,500 sq ft multi-brand stores are compartmented, and here is the ordinary shape of one:
Main floor, 1,400 sq ft at 12 ft: 1,400 x 12 = 16,800 cubic feet, about 476 cubic metres.
Brand room with a door, 300 sq ft at 12 ft: 300 x 12 = 3,600 cubic feet, about 102 cubic metres.
Collector lounge, 350 sq ft at 11 ft: 350 x 11 = 3,850 cubic feet, about 109 cubic metres.
Private viewing room, 150 sq ft at 10 ft: 150 x 10 = 1,500 cubic feet, about 42 cubic metres.
Back of house, 300 sq ft at 10 ft: 3,000 cubic feet, about 85 cubic metres - excluded entirely.
Add the four customer volumes and you have about 729 cubic metres, spread across four rooms rather than pooled in one. And the largest single volume, the main floor at 476, is under half a Vaayu's rating.
That is the recurring finding of this section stated at its clearest: a compartmented store is several small volumes rather than one big one, and several small volumes are easier and cheaper to do properly than one large one. Each room gets a source appropriate to its own size, each runs at its own level, and none of them is working anywhere near a machine's limit. The main floor takes one Vaayu at ₹11,999 at a low setting on a timer. The 102 cubic metre brand room and the 109 cubic metre lounge each take a small ultrasonic - a Sukoon at ₹1,899 with the water-based Hotel Collection from ₹299 - at a lower level. The 42 cubic metre viewing room takes a Boond at ₹899, lower again. And the back of house takes nothing.
The other case, and it deserves an honest paragraph. Some 2,500 sq ft stores really are one open volume: a single retail hall with brand areas defined by casework rather than walls, no doors anywhere except to the back of house. Then you have 850 cubic metres at 12 ft or 991 at 14, and a single machine is at or near full stretch. Two things follow. First, a single unit will produce a gradient across a 71 ft diagonal no matter how it is set, so the practical answer is often two sources running the same register at the same level - which is one zone with two sources, not two zones, and the distinction matters because two sources at two different levels in one connected volume simply mix into an uncontrolled average. Second, this is the point at which you should be talking to somebody with your plan in hand rather than reading a page. SOSA does not publish consumption rates or running costs, so nobody can honestly tell you on a web page what two units in one hall will cost you to run: that is a WhatsApp conversation at +91 96192 18531.
And the ducted machines, for completeness: Aangan at ₹25,999 covers approximately 8,000 to 10,000 sq ft and Meenar at ₹38,500 approximately 12,000 to 18,000 sq ft. At 2,500 sq ft you are still under a third of the smaller remit, and ducted scenting distributes to wherever the ducts go - which in a multi-brand store usually includes the stock room, the office and the bench, the exact rooms that should get nothing.
So: a 300 sq ft brand room with a door that shuts is a zone. A 300 sq ft brand area defined by two plinths and a change of flooring is not. The first has about 102 cubic metres of its own air. The second has a share of the main floor's 476, exactly like every other part of the floor, and no amount of intention makes it otherwise.
The physical argument against scenting brand corners separately. Put register A in one corner and register B forty feet away on the same open floor, and you have not created two zones. You have created three smells: A near A, B near B, and in the aisle between them a mixture that nobody composed, nobody chose and nobody can control, which changes hour by hour with the air conditioning and the door traffic. A customer walking the floor experiences a sequence of appearances, disappearances and collisions - and a level that changes as you move is a level a customer notices. The moment they notice it, they can name it, and that is the failure this whole bank is built to avoid. The failure in luxury retail is not a room that smells of nothing. It is a customer who can name what the room smells of.
The same argument applies, more sharply, to the doorway between two doored rooms that have been given different registers. The seam is met every time the door opens, which in a busy store is constantly, and it is the single most reliable way to make a carefully built environment feel assembled out of parts rather than designed as a whole. Hence the rule that governs every multi-room page in this bank: same register, different levels, never two registers.
The identity argument, which is specific to multi-brand. Suppose the physics were on your side. You still should not do it, because of whose identity a scent would be expressing. In a multi-brand store, each maison arrives with its own carefully controlled identity - its casework, its materials, its signage, its display language. Attaching a fragrance character to one brand's corner puts an olfactory identity onto a brand that did not choose it, in a medium it does not control, in your building. That is not yours to do. The retailer's register is the retailer's, and it should read as the character of the store - present everywhere a customer goes, identical in every area, belonging to no supplier.
SOSA is an independent Indian fragrance house and is not affiliated with, endorsed by or connected to any watch manufacturer. No SOSA register represents, evokes or is licensed by any maison, and no honest page would suggest otherwise.
What real zoning looks like, then. Four positions on a ladder, one register, levels descending with enclosure and dwell:
1. Main floor at the top of the ladder, set for the ninety-minute appointment and then one notch off, and still the highest thing in the building.
2. Doored brand room or consultation room, one step down, because 102 cubic metres behind a shut door accumulates what 476 does not.
3. Collector lounge, at or below that, because it holds the longest dwell in the building and its rugs and upholstery are reservoirs that hold what they are given.
4. Private viewing room, lowest of all, because 42 cubic metres holding two or three people for an hour is the fastest-accumulating space you own.
Then zero in the back of house, the bench, storage, the safe and the office. Write those five positions on the drawing as named rooms with numbers, not as a principle in somebody's head, because a principle gets reinterpreted in month seven by a well-meaning new floor manager and a drawing does not.
One last note on the open floor. If a distant part of your 476 cubic metre main floor is genuinely flat - behind a full-height display run, or at the end of a 71 ft diagonal - the answer is a second source in that area running the same register at the same level, not a different one and not a higher one. That is still one zone. Two sources, one zone, one level: the distinction is the whole discipline.
The brief for a multi-brand house register is: dry, clean, unsweet, unsigned, and quiet enough to be received as the building. Every one of those words is doing work.
Dry, because dry registers read as material and structural rather than decorative, and a structural register survives dilution across a 71 ft floor while still reading as itself.
Clean, because a clean register is the one thing every maison's own identity can sit on top of without argument. It behaves like white walls and neutral light: a background that flatters everything and competes with nothing.
Unsweet, because sweetness is the single characteristic that makes a retail room read as a shop rather than as a room, and in a room presenting several luxury identities, reading as a shop is exactly what you cannot afford.
Unsigned, because a strongly signed register is a statement, and a statement in a multi-brand store is a fourth voice in a conversation that already has three. The moment a client thinks that is a fragrance, the room has become a display - and a display is precisely what a serious buyer is trying to see past when they are looking at an object under a light with a loupe.
Quiet, because of dwell. The ninety-minute appointment is the longest sit in retail and it happens in your building every day. A level that reads considered in the first ten seconds is insistent by minute sixty. Set for the appointment, take one notch off, and accept that the entrance reads as almost nothing.
That brief points to the dry, quiet end of the water-based Hotel Collection - and the specific registers are discussed in the section below - rather than to anything characterful, floral, sweet or theatrical.
Now the thing a house register actually buys you, because it is not what the trade usually claims. It buys consistency. A client who visits in March and returns in September meets identical air and recognises the place without ever being able to describe why. That recognition is the product, and it is free once the level is set correctly and written down. Consistency makes a signature. Not strength, not uniqueness, not price. Which is also the honest answer to the owner who asks whether they should commission something exclusive: bespoke composition is a real SOSA service, discussed on WhatsApp rather than priced on a page - but the cheaper honest answer comes first, which is that one of the seven registers held consistently already is a signature, because consistency is what makes one.
And the claim ceiling, which a multi-brand retailer deserves stated out loud. I will not tell you that a house register sells watches, raises average transaction value, converts browsers or increases footfall, because nobody can tell you that honestly and SOSA claims none of it. What ambient scent research supports is improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes. That is real, it is modest, and in a multi-brand store it is worth having for a reason specific to your format: your register is one of the very few elements of the environment that is yours rather than a supplier's, and it is the same in every corner of a building that is otherwise divided up.
No claim is made about what a scent does to a person - no mood, no comfort, no decision, no internal state. And fragrance adds scent; it never removes odour. If the store has a stale Monday morning, a damp lounge rug after monsoon or a back office sharing a return grille with the floor, the order is source, then ventilation, then cleaning, then fragrance - and never reducing air exchange so that fragrance lasts longer.
- Mark dwell minutes and every door that stays shut - the doors are your only zones.
- Compute each volume: area x ceiling height, then divide by 35.3.
- Pick one house register, quiet and unsigned, for every space a customer enters.
- Set levels descending by enclosure, write them on the drawing, give the back nothing.
The house register, and why it has to be the quietest thing in a multi-brand store
Which register, then, for a store that carries several names and must not take sides. There are seven in the water-based Hotel Collection, each SOSA's own hotel-inspired interpretation - SOSA is independent and not affiliated with, endorsed by or connected to any hotel brand, and it is worth saying plainly rather than trading on somebody else's name.
For a multi-brand floor the field narrows to three, and the reason is neutrality rather than taste.
Quiet Luxury - white tea, bergamot and cedar - is the default, and in a multi-brand store it is more than a default. Hushed, polished, unsweet, and almost impossible to read as a statement, which is exactly the quality you want in a room where several identities are being presented side by side. If somebody handed me a 2,500 sq ft multi-brand plan and no other information, this is the register I would specify.
White Tea Serenity - white tea, aloe and cedar - is the answer for a pale, glassy, contemporary store with a lot of stone and daylight. It reads as clean rather than as scented, which is the closest thing in the collection to a register that is not there at all, and in a store whose job is to flatter several brands' casework that absence is a virtue rather than a shortfall.
Forest Suite - cedarwood, vetiver and green leaves - is the driest and most structural of the three, and the one that travels best across a long floor. Because it reads as material rather than decorative, a mixed public receives it as part of the building, which is the cleanest way for a house register to behave when the building contains several houses.
Old-World Glamour - amber, violet and woods - is a legitimate choice only if the whole store is genuinely heritage in character: dark timber, brass, deep seating, some age to the room. Held lower than anything else on this list, because plush accumulates over a ninety-minute sit faster than dry does, and lower again in the lounge and the viewing room. In a store where the brand areas differ sharply in style, it is the riskier pick, because it has a point of view and a point of view is what a multi-brand register should not have.
The three to leave alone on a multi-brand floor. Lobby Bar - citrus, pepper and amber - is theatrical, and turning a theatrical register down gives you a quiet theatrical register rather than a neutral one. Tea Garden - jasmine, green tea and white tea - is the least risky floral in the collection because the jasmine sits inside the tea rather than on top of it, but a floral on a retail floor still reads as a decision somebody made, and in multi-brand the whole aim is a register that reads as nobody's decision. Warm Welcome - citrus, floral and sandalwood - is a gracious hotel threshold register and the beginning of the sweetness problem in retail.
There is no leather register in the SOSA range and this page will not invent one. The palette is these seven plus five reed scents, and if leathery is the direction in your head the nearest honest answers are Forest Suite and Old-World Glamour.
Two practical system notes for a store this size. The seven above are water-based and run in the ultrasonics; the Vaayu and the ducted machines run four hotel-inspired waterless blends supplied with the machine as one of three bundle choices, and the ₹299 water-based bottle never goes into a Vaayu. In a four-volume store the commonest arrangement is a Vaayu on the main floor and ultrasonics in the enclosed rooms, which means two systems in one building - so have the conversation before you buy, so that the rooms agree with each other rather than arguing across a doorway.
And what I will not do: rank these seven on measured throw or longevity. SOSA does not publish that comparison, and the variables that dominate - your 476 cubic metres, your ceiling, your ventilation, your storefront, your hard surfaces and your setting - are yours rather than the blend's.
| Scent | Why it suits the mood |
|---|---|
| The house register · everywhere a customer goes | Quiet Luxury unless the fit-out argues otherwise - white tea, bergamot and cedar, hushed and unsweet and almost impossible to read as a statement. It is the one element of the environment that belongs to the retailer rather than to a supplier, which is exactly why it must be neutral enough not to argue with any brand's own identity. |
| Main floor · about 476 cubic metres, highest level | One Vaayu at ₹11,999 placed inward and out of the entrance airstream, on the timer for trading hours. If a distant part of a 71 ft floor is genuinely flat, add a second source running the same register at the same level - that is one zone with two sources, not two zones. |
| Each doored room · 102, 109 and 42 cubic metres, descending | The same register, one step down for a doored brand or consultation room, at or below that for the lounge whose rugs and upholstery are reservoirs, and lowest of all in the private viewing room - a smaller, more enclosed volume holding fewer people for longer. A Sukoon at ₹1,899 or a Boond at ₹899 with the water-based Hotel Collection from ₹299. |
| A register per brand · the one thing not to do | Brand corners on an open floor share the same air, so two registers make a third smell in the aisle that nobody composed and nobody controls - and a level that changes as a customer walks is a level they can name. It also attaches an olfactory identity to a maison that did not choose it. One register, four levels, no exceptions. |
So the plan, assembled, for an ordinary compartmented 2,500 sq ft multi-brand store. First the free work - source, ventilation, cleaning - because fragrance adds scent and never removes odour, and a register laid over a stale room makes a third smell rather than cancelling the first. Then the volumes, computed and written on the drawing. Then the sources.
Main floor, about 476 cubic metres. One SOSA Vaayu at ₹11,999, placed inward and out of the entrance airstream, running trading hours on the Bluetooth timer. Waterless cold-air nebulising of undiluted oil - no water, no humidity, no wet residue - which is the honest reason a store holding leather straps, open trays and a bench prefers it to a cool-mist machine that puts moisture into the air; a design preference, not a protection claim. Approximately 1000 cubic metres of connected air, 400ml tank, freestanding or wall and HVAC mount, DC 12V / 1A at 5W so it needs a live socket where you actually want it, CE, RoHS and SGS. At 476 against 1000 it is working at under half, which is an instruction to run it low.
The doored brand room at about 102 and the lounge at about 109. A SOSA Sukoon at ₹1,899 each, running the water-based Hotel Collection from ₹299 with 100ml refills at ₹999, both one step below the floor. If the lounge runs from eleven in the morning until nine at night, a SOSA Megh at ₹3,499 with its 6 litre tank spares somebody a refill in the middle of an evening.
The private viewing room at about 42. A SOSA Boond at ₹899, lowest level in the building. This is the room where the ninety-minute appointment actually happens and it is the fastest-accumulating space you own.
Washrooms and staff areas. A reed from ₹749 - Morning Freshness at ₹749 is Malabar lemon, mint and eucalyptus and is the washroom answer, Mountain Breeze at ₹849 is Himalayan pine, sage and cedar and is closest to a boutique's direction, and Garden Bloom at ₹799, Evening Calm at ₹799 and Fresh Brew at ₹849 belong where nobody is being hosted. The 130ml is from ₹1,249, refills are ₹2,399 for 300ml and ₹3,499 for 500ml, and a reed lasts about 6 to 10 weeks, with no plug and nothing to switch off.
Bench, workshop, stock storage, the safe and the office. Nothing at all. Write them as named rooms on the drawing.
The pack of seven 15ml Hotel Collection bottles at ₹1,799 is the sensible way to audition a house register in your own building - run each for five days rather than an afternoon, and judge it on a Monday morning rather than a Friday evening. And the two systems are not interchangeable: the ultrasonics are water-based, the Vaayu and the ducted machines run waterless nebulising oil, and the ₹299 bottle never goes into a Vaayu.
If your store is a single connected floor rather than a set of rooms, the sizing and placement argument for that shape is at how to scent a 1,500 sq ft premium watch boutique. If you are choosing between the two systems rather than drawing zones, that is what scenting system makes sense for a 1,000 sq ft watch showroom. And if you also run a small satellite location, its arithmetic is at how to scent a 500 sq ft luxury watch boutique.
What SOSA does not publish and this page will not invent: consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order quantity or installation lead time. Those depend on run hours, connected volume, setting and how many volumes you chose to scent - and in a four-volume store that last one is entirely your decision.

Bulk orders are welcome, custom label or logo on product is available, and bespoke composition made only for your store is a real SOSA service discussed there rather than priced on a page - though the cheaper honest answer comes first, which is that one of the seven registers held consistently already is a signature, because consistency makes a signature and uniqueness does not.
The SOSA scenting range
SOSA sells two different systems and one of the commonest mistakes is mixing them up. Size by the connected air volume of the room you are actually scenting - which in a boutique means the connected retail floor plus any viewing room that has a door of its own - floor area multiplied by ceiling height gives cubic feet, and cubic feet divided by 35.3 gives cubic metres. A door that stays shut ends one volume and begins another.
| Machine | System | What it is for | Price |
|---|---|---|---|
| SOSA Boond | Ultrasonic · water-based | A small desk or corner unit for one enclosed room - runs the water-based Hotel Collection | ₹899 |
| SOSA Sukoon | Ultrasonic · water-based | A larger ultrasonic for a reception or consultation room - Hotel Collection from ₹299 | ₹1,899 |
| SOSA Megh | Ultrasonic · 6L tank | A large-tank ultrasonic for a bigger lounge that runs all day | ₹3,499 |
| SOSA Vaayu | Waterless cold-air nebulising | The commercial machine - approx 1000 m3 of connected air, Bluetooth app and timer, no water and no humidity | ₹11,999 |
| SOSA Aangan | HVAC nebulising | Ducted scenting for approximately 8,000 to 10,000 sq ft | ₹25,999 |
| SOSA Meenar | HVAC nebulising | Ducted scenting for approximately 12,000 to 18,000 sq ft | ₹38,500 |
Two systems, and they are not interchangeable. The ultrasonics - Boond, Sukoon and Megh - run the water-based Hotel Collection from ₹299. Vaayu and the HVAC machines run waterless nebulising oil; the ₹299 water-based bottle never goes into a Vaayu. SOSA blends are SOSA's own hotel-inspired interpretations and SOSA is independent and not affiliated with any hotel brand. A portion of every order supports girl-child education through Nanhi Kali.
- Vaayu ₹11,999 - waterless cold-air nebulising, approx 1000 m3 connected air, Bluetooth app and timer, 400ml tank, freestanding or wall / HVAC mount, DC 12V / 1A, 5W, mains powered, CE / RoHS / SGS.
- Aangan ₹25,999 for approximately 8,000 to 10,000 sq ft and Meenar ₹38,500 for approximately 12,000 to 18,000 sq ft - both ducted into HVAC.
- The ultrasonics - Boond ₹899, Sukoon ₹1,899, Megh ₹3,499 - run the water-based Hotel Collection from ₹299, with 100ml refills at ₹999.
- Not published, and therefore never stated on this page: consumption rate, refill frequency, monthly running cost, machine lifespan, installation lead time or any minimum order. Those go to WhatsApp +91 96192 18531.
Versailles
A watch boutique is a room where somebody sits down for an hour and a half to make a decision worth more than most people's cars. That is the fact that should govern everything about the air in it. Not the doorway, not the first impression, not the ten seconds a passer-by gets - the ninety minutes. A level that is lovely at minute one is tiring at minute sixty, and tiring is the last thing you want in the room where the tray comes out.
So my advice to every boutique owner is the same and it is slightly annoying: go lower than you want to. In luxury retail the tell is not that a room smells of nothing; it is that a customer can name what it smells of. The moment somebody can say "oh, that's a fragrance", the room has stopped being a place and started being a display, and a display is exactly what a serious buyer is trying to see past.
Two other honest things. Fragrance adds scent - it never subtracts one - so if the store has a source problem, a leather smell that has gone sour, a stale morning, a workshop bench that vents into the floor, no bottle solves it; air and cleaning do. And I will not tell you that a scent sells watches. Nobody honestly can. What a held, quiet, consistent room does is make a boutique easier to be in for ninety minutes and easier to recognise the second time - and in this trade that is worth having on its own terms.

Fragrance adds scent and does not remove, neutralise or purify odour, and no SOSA product makes any health, antibacterial or air-purifying claim. No SOSA product is an air-treatment device, and no claim is made here about any effect on a customer, a purchase decision, a transaction value or a product on display.
