Buying a Pre-Owned Watch at Auction: A Practical Checklist

1. Reference number and serial number: know the difference

• The reference number identifies the model (for example, a specific dial, case and bezel combination).
• The serial number identifies that individual watch and can help date it.

Ask the auction house to state both, or to photograph where they appear. Check that the reference matches the features you see in the photos: dial layout, case size, bezel, bracelet. A reference that doesn’t match the details is a red flag.

2. “Box and papers”: what exactly is included?

“Box and papers” can mean anything from a complete original set to a generic box. Ask specifically:

• Is the warranty card or certificate original to this watch? Does its serial number match the case?
• Are there purchase receipts, service records or manuals?
• Are the box and outer box original to the model and era?

Matching papers support value and authenticity. Papers that don’t match the watch are not a plus.

3. Service history

A mechanical watch needs periodic servicing. Ask:

• When was it last serviced, and by whom (the manufacturer or an independent watchmaker)?
• Is there a receipt?
• Was anything replaced during service?

If there is no service history, budget for a service after purchase. Depending on the brand and complexity, that can be a significant cost. Factor it into your maximum bid.

4. Originality: dial, hands, bezel, crown, bracelet

This is where value is won or lost.

• Dial: original, refinished (“redial”) or a service replacement? Refinished dials usually reduce collector value.
• Hands and bezel insert: original to the watch or replaced?
• Crown and pushers: correct for the reference?
• Bracelet or strap: original, period-correct or aftermarket?

A watch assembled from parts of different watches is sometimes called a “Frankenwatch.” It may run perfectly, but it is not what a collector expects from the reference. Ask the house to state in writing which parts it considers original.

5. Case condition: polished or unpolished

Collectors often prefer an unpolished case with honest wear over a heavily polished one, because polishing removes metal and softens the original lines. Look at the edges of the lugs and the case flanks in the photos. Ask whether the case has been polished.

6. Movement photos and running condition

Request a photo of the movement (the caseback opened). It helps confirm the calibre is correct for the model. Be careful with language like “running at time of cataloguing.” It means the watch ran when it was checked. It does not mean it keeps accurate time, and it is not a guarantee. Water resistance on a pre-owned watch should never be assumed. Treat any watch as not water-resistant until it has been pressure-tested.

7. Manufacturer and archive documentation

Some manufacturers offer archive services that confirm a watch’s production details; Omega’s “Extract from the Archives” is one example. If a lot comes with such a document, confirm that it matches the serial number. If you are buying a significant watch, you can ask whether the house will allow an independent watchmaker to inspect it before payment or within a defined window.

8. The true cost

Add the buyer’s premium, sales tax, insured shipping and a realistic service budget to your bid. A $3,000 hammer price is not a $3,000 watch. Set a hard maximum that includes everything, and stick to it. See my notes on the buyer’s premium and what happens after the hammer falls.

9. Remedies and payment

Before bidding, read the terms. What does the house guarantee about authenticity? Is there a window to raise a problem? What payment methods are accepted, and which ones offer you any protection if something goes wrong? Ask questions now, not after the sale.

Quartz, mechanical and automatic

Know which you are bidding on. A quartz watch runs on a battery and is usually less costly to maintain. A mechanical watch is wound by hand, and an automatic winds itself with the motion of your wrist; both need periodic servicing. Vintage quartz models have their own collectors, but parts for some older quartz movements can be hard to find, so ask about serviceability too.
