A buyer's premium is a percentage of the hammer price that the auction house adds to the winning bid. The buyer pays it; the seller never sees it. At the major houses it is 28 to 30 percent on a typical watch. At Grey Market it is a flat 7 percent. Set your ceiling with it already subtracted.
Two Prices for One Watch
Every auction result has two numbers behind it. The hammer price is the winning bid, the figure called when the lot closes and the one that appears in the results. The total price is what the buyer actually pays: the hammer, the buyer's premium, sales tax where it applies, and shipping. The premium is set by the house as a percentage of the hammer and published in the conditions of sale before the auction opens. It is not negotiable, at any house, for any bidder.
It was not always part of the invoice. Until the 1970s the house was paid by the consignor alone, through a commission deducted from the hammer. Christie's introduced a buyer's premium in London in 1975 and Sotheby's followed within the year. Charging both sides let the houses compete for consignments by lowering, and in some cases waiving, the seller's commission, while the buyer's side carried a growing share of the cost. Fifty years on, the buyer's premium is the larger of the two fees at every major house.
The practical consequence: when a Daytona is reported to have sold for $50,000 at auction, the buyer's invoice was closer to $64,000.
What the Auction Houses Charge
Published rates as of September 2026. Every house tiers its premium so the percentage falls as the hammer rises, which means the top rate is the one that applies to nearly every watch. Rates change, and online-only sales sometimes carry their own, so the conditions of sale for the specific auction are the final word.
| House | Premium on a typical watch | Tiers |
|---|---|---|
| Christie's | 28% | To about $2 million; 22% on the next tier; 15% above |
| Sotheby's | 28% | To $2 million; 22% to $8 million; 15% above |
| Phillips | 29% | Same tiers; the dominant house in watches since the Bacs & Russo partnership |
| Bonhams | 30% | From October 1, 2026, on roughly the first $33,000; 28% to about $670,000 |
| Heritage | 20% | 22% on some online-only sales |
| Grey Market | 7% | Flat, no tiers |
The headline rate is rarely the whole fee. Salerooms add an overhead or administration charge of a point or two, a surcharge for bidding through a third-party online platform, and, outside the United States, VAT on the premium itself. Read the fee section in full.
What the Online Platforms Charge
Most watches do not change hands at Christie's. They move through online auctions, fixed-price marketplaces and forum deals, and each has its own version of the same fee, sometimes on the buyer, sometimes on the seller, sometimes split. What matters to the price is the total, because a fee on the seller is priced into the ask. The tables below show total fees, both sides combined, at four price points: fees only, paid by bank transfer, with sales tax, shipping and card surcharges excluded. Schedules were checked in September 2026.
Auction against auction
Sorted by the fee on a $5,000 watch, the price where most of our lots trade.
| Platform | Who pays | $1,500 | $5,000 | $15,000 | $30,000 |
|---|---|---|---|---|---|
| Grailzee | Buyer 5%, $250 minimum, $5,000 cap; seller $99 listing | $349 | $349 | $849 | $1,599 |
| Grey Market | Buyer 7%; seller nothing | $105 | $350 | $1,050 | $2,100 |
| eBay, auction format | Seller 15% to $1,000, 6.5% to $7,500, 3% above | $183 | $410 | $798 | $1,248 |
| Loupe This | Buyer 10%; seller fee not published | $150 | $500 | $1,500 | $3,000 |
Below $5,000, Grey Market is the cheapest auction in the table. Grailzee and Grey Market are a dollar apart at $5,000 and part ways on either side of it: Grailzee's $250 minimum makes it the most expensive auction here for anything under about $3,500, and its $5,000 cap makes it the cheapest above that. eBay's sliding scale overtakes us above about $9,000. Loupe This costs more than Grey Market at every price. What the 7 percent buys at any price is the same: an independent verifier before the seller is paid, escrow, and a full refund if the watch fails.
Marketplace against marketplace
Same sort. The two forum rails are included because a private sale is the alternative most sellers actually weigh against a marketplace.
| Platform | Who pays | $1,500 | $5,000 | $15,000 | $30,000 |
|---|---|---|---|---|---|
| Grey Market Exchange | 1.25% each side, $25 minimum each | $50 | $125 | $375 | $750 |
| Forum deal, Escrow.com by wire | 2.6%, $50 minimum; split by agreement | $60 | $140 | $370 | $730 |
| Forum deal, PayPal Goods & Services | Seller 2.99% plus $0.49 | $45 | $150 | $449 | $897 |
| Chrono24, private seller | Seller 6.5% | $98 | $325 | $975 | $1,950 |
| eBay, fixed price | Seller 15% to $1,000, 6.5% to $7,500, 3% above | $183 | $410 | $798 | $1,248 |
| Bezel | Seller 12%, $225 minimum; buyer $79 | $304 | $679 | $1,879 | $3,679 |
Against the marketplaces the Exchange is cheaper at every price point, by a factor of two to five. The only rows that come close are the forum deals, and those are bare payment rails: a PayPal transaction on a $1,500 watch saves $5, Escrow.com pulls ahead above about $10,000, and neither includes authentication or anyone in the middle when the watch that arrives is not the watch in the photos. That is where most of the cases in our guide to avoiding watch scams begin.
The fee also buys different things. eBay authenticates from $2,000 up at no charge; Grailzee includes authentication; Chrono24 sells it for $249 and Bezel bundles it into the seller's 12 percent. On Grey Market, verification and escrow are part of every auction sale, and available on the Exchange for buyers who want the watch inspected before their money is released.
One Watch, Three Invoices
A Rolex GMT-Master 1675 hammers at $10,000. Domestic shipping, before sales tax, paid by wire.
| Major house, 28% | Loupe This, 10% | Grey Market, 7% | |
|---|---|---|---|
| Hammer | $10,000 | $10,000 | $10,000 |
| Buyer's premium | $2,800 | $1,000 | $700 |
| Total before tax and shipping | $12,800 | $11,000 | $10,700 |
Bidders should read the table from right to left. If $12,800 is the most you will spend on that 1675, your ceiling on the hammer is $10,000 at a 28 percent house and $11,960 at Grey Market. The same budget reaches nearly 20 percent further, or buys the same watch for $2,100 less.
The rule is simple: maximum hammer bid = all-in budget ÷ (1 + premium rate). Work it out before the lot opens and write it down. The last two minutes of a live auction are not the moment to be doing division. Our guide to bidding builds the rest of a bidding plan around that number.
The Rest of the Invoice
- Sales tax. Where it applies, it is charged on the buyer's total, so the premium is taxed along with the hammer. On a $12,800 total shipped to California, that is a little over $1,100 more. The rate is the same wherever you buy; only the base it is applied to differs. Forum deals usually collect none, which is a large part of their apparent saving and a liability that has not gone away.
- Shipping and insurance. The houses quote it after the sale, and an insured shipment of a five-figure watch is rarely under $150. Grey Market ships from the verifier to you once the watch has passed inspection, and the estimate is shown on the listing before you bid. Our guide to shipping a luxury watch covers what that insurance actually needs to say.
- Payment method. Salerooms take a wire at no charge and often refuse or surcharge cards above a threshold. At Grey Market, ACH and wire are free; paying by card adds a 2.9 percent processing fee.
- Authentication. At a saleroom, the catalogue description is the authentication, and the buyer's recourse after the sale is whatever the conditions of sale allow. On Grey Market, every sold watch goes to an independent verifier before the seller is paid, your funds sit in escrow until it passes, and a watch that fails is refunded in full. About one submission in three does not make it to the block in the first place. There is no separate line for any of this. It is what the 7 percent covers.
Where the Seller Stands
At a traditional house, the consignor pays a commission on the hammer, negotiated against the strength of the consignment, plus charges for photography, insurance and, sometimes, an unsold lot. On the marketplaces the seller carries most or all of the fee, as the table above shows. At Grey Market there is no seller commission and no listing fee. The seller receives the full hammer price. Their only cost is the insured shipment to our verifier, deducted from the payout, and there is no charge at all if a submission is declined. If you are weighing the channels, our comparison of consignment, direct sale and auction puts the fee next to the other trade-offs.
That is the whole schedule on the auction side: 7 percent from the buyer, nothing from the seller. It is published, it is the same for every lot, and it is not something anyone negotiates.
The Grey Market Exchange
Not every watch belongs at auction, and not every collector wants to wait for a sale date. The Grey Market Exchange is the fixed-price counterpart: a seller lists a watch at their price, a verified buyer pays through the same escrow, and the watch ships. The fee is split evenly and kept small: 1.25 percent from the seller and 1.25 percent from the buyer, with a $25 minimum on each side. Card payments carry the same 2.9 percent processing fee as the auction, and buyers who want the watch inspected before their funds are released can add independent verification.
On the $5,000 watch in the table, that is $125 between the two parties, against $325 to $679 on the marketplaces and $350 at our own auction. The difference between the two products is the room and the reserve: an auction brings competing bidders and a price the market sets; the Exchange brings a price the seller sets and a buyer who does not want to wait. Both run through the same identity-verified accounts, the same escrow and the same verifier.
Why the Number Is Lower Here
A saleroom's premium pays for specialists, a printed catalogue, previews in several cities, a room on sale day, and a settlement cycle measured in weeks. That machinery earns its keep on a six-figure Patek with a story to tell. A verified marketplace auction runs on a smaller footprint and passes the difference to both sides. What it offers instead is a room of identity-verified bidders, escrow, independent authentication before money moves, and a settled price that lands 21 points closer to the hammer.
Neither model is wrong. They are priced for different watches. For the references most collectors actually buy and sell, the premium is the fee, and it is worth comparing before you bid. Our guide to buying a pre-owned luxury watch covers the other questions to settle before that point.
Questions People Ask
Is the buyer's premium negotiable? No. It is published in the conditions of sale and applied to every lot, at every house, and at Grey Market.
Does the seller receive any of it? No. The premium is the house's revenue. The seller receives the hammer price less the seller's commission and costs, or, on Grey Market, the full hammer price.
Is tax charged on the premium? Where sales tax applies, yes. The taxable amount is the buyer's total, including the premium.
Do auctions without a buyer's premium exist? Occasionally, as a promotion. Look at what replaces it: a higher seller commission is usually priced into higher reserves, so the cost moves rather than disappears.
How do I see the total before I bid on Grey Market? Every listing shows the premium, the estimated tax and the shipping estimate beneath the bid box, and the exact charge is confirmed before your payment method is run when the auction closes. The FAQ has the full fee schedule in one place.
The Bottom Line
The buyer's premium is the largest cost in an auction purchase after the watch itself, it is never negotiable, and it varies more between venues than almost anything else about the sale: 28 to 30 percent at the salerooms, 5 to 10 percent on the online platforms, 7 percent here. Know the rate before you register, divide your budget by it before you bid, and read the rest of the fee schedule for what the headline number leaves out. What you are paying for, in the end, is the room and the assurance that the watch is what it says it is. Pay for those; do not pay for the catalogue.
