Buying watches at auction as a dealer

Auctions offer stock you won't find elsewhere and a public record of what watches really sell for. They also make it easy to overpay in the heat of the moment. Here's how to set your limit before the bidding starts, and hold to it.

Auctions give a dealer two things at once: access to watches that rarely come up privately, and a public record of what watches actually sell for. They also create the conditions for overpaying, with competition, a clock, and a room or screen full of people who want the same lot. Buying well at auction is mostly about doing the work before the bidding starts.

Know what you're bidding on

  • Read the catalog description carefully. Note exactly what the house says about the watch, and what it doesn't. Language that is vague about originality, service, or accessories is telling you something.
  • Get the condition report. Most houses provide one on request. It's usually more candid than the catalog entry. Ask specific questions if something matters to your resale, such as whether the dial is original or when the watch was last serviced.
  • Inspect if you can. Viewings before a sale let you check the watch yourself. When you can't attend, ask for extra photos of the details you need to see.
  • Check the accessories. Box, papers, extra links, and service paperwork change what a watch will resell for. Confirm what's included in the lot.

Read the conditions of sale

Every auction house publishes terms that govern what you're agreeing to when you bid. Read them for each house, because they differ.

  • The buyer's premium. A charge added to the hammer price and paid by the winning bidder. It's part of your cost, and it can be substantial.
  • Tax. Sales tax may apply to the hammer price, the premium, or both, depending on the house and where the watch is delivered.
  • Other charges. Online bidding platforms, shipping, insurance in transit, and payment method fees can all add to the total.
  • Returns and guarantees. Many lots are sold as they are, with limited remedies. Know what, if anything, you can do if the watch isn't as described.
  • Payment and collection deadlines. Houses expect prompt payment and collection, and may charge storage after a deadline. Plan your cash before you bid.

The auction consignment article covers the same process from the seller's side, which helps explain how estimates and reserves are set.

Set your maximum bid before the sale

Your limit comes from your resale, not from the estimate. Start with a conservative expected sale price for the watch through the channel you'll use, take off your selling costs, prep, and target profit, and you have the most you can pay in total. Then remove the buyer's premium and any other auction charges from that total to find your maximum hammer bid.

Illustrative exampleTurning a max buy into a maximum hammer bid

A watch you expect to resell for $8,000 through a channel charging a 6% selling fee and 3% processing. You'll spend $300 on prep, $60 getting it home, and want a 15% margin. The auction's buyer's premium in this example is 25% of the hammer price.

Expected sale price
$8,000.00
Selling fee (6%)
−$480.00
Payment processing (3%)
−$240.00
Shipping out and insurance
−$125.00
Net proceeds
$7,155.00
Prep
−$300.00
Shipping in
−$60.00
Target profit (15% margin)
−$1,200.00
Most you can pay in total
$5,595.00
Buyer's premium (25% of hammer)
−$1,119.00
Maximum hammer bid
$4,476.00

The premium is charged on the hammer price, so the maximum hammer bid is the total divided by 1.25, not the total minus a quarter of it. Bidding $5,595 because that's your max buy would leave you paying $6,993.75 once the premium is added. Run the first part with your own numbers, then take your auction's own premium out of the result.

Bid with discipline

  • Write your limit down and don't revise it upward during the sale. The number you worked out calmly is better than the one you'd pick under pressure.
  • Remember the premium when you watch the price. The hammer price on screen isn't what you'll pay.
  • Use absentee or maximum bids if you're likely to get drawn in. They bid for you up to your limit and no further.
  • Let lots go. Other bidders may be collectors who don't need a margin. You can't win against them and shouldn't try.

Use results even when you don't buy

Published auction results are useful pricing evidence. Note what comparable watches hammered for and what they cost with the premium, and compare them with what similar watches sell for through your own channels. Over time, this shows you which auctions offer genuine buying opportunities and which simply set the retail price.

Common questions

What is a buyer's premium at a watch auction?

It's a charge the auction house adds on top of the hammer price, paid by the winning bidder. Rates and any tax treatment are set in each house's conditions of sale, so read them for every auction you bid in.

How do I decide how much to bid at a watch auction?

Work out the most you can pay in total from your expected resale price and costs, then take the buyer's premium and any other auction charges out of it. What's left is your maximum hammer bid.

Can I return a watch bought at auction?

Often only in narrow circumstances. Many auction terms sell lots as they are, with limited remedies set out in the conditions of sale. Check the terms before you bid, not after you win.
