The short answer
Find the brand, model and reference number, gather the box, papers, receipts and service records, and check that the watch runs and keeps time. Clean it lightly, photograph the dial, case, caseback and clasp, and check recent sold prices for the same reference in the same condition. Sell through a channel with authentication or buyer protection for valuable watches, and ship insured.
Step 1: identify the watch
Look for the reference or model number on the caseback, between the lugs, on the papers or on the box label. The reference number identifies the exact model and is what serious buyers search by. Note the movement type: quartz (battery), automatic or manual wind. Our guide to watch values explains where to look.
Step 2: prepare smartwatches
For a smartwatch, back it up, then unpair it from your phone using the maker's official steps. On an Apple Watch, unpairing in the Watch app also removes Activation Lock. For other brands, remove the watch from your account and then factory reset it. Check that it starts at the setup screen and asks for no account of yours.
Step 3: check that it works
- Quartz: check it runs. A dead battery is common; a fresh battery from a watch shop lets you show it working, but ask them not to open a valuable watch unnecessarily.
- Automatic and manual: wind it, then watch it over a day or two and note whether it gains or loses time.
- Functions: date change, chronograph pushers, bezel rotation and the crown.
- Water resistance: do not claim it unless it has been pressure tested recently.
If a mechanical watch stops or runs badly, describe it rather than guessing; some buyers want watches to service.
Step 4: clean it lightly
Wipe the case and bracelet with a soft microfiber cloth. Use a soft brush to clear dirt from bracelet links if the watch is water resistant and the crown is closed. Do not polish the case; collectors often prefer original, unpolished cases, and polishing cannot be undone.
Step 5: gather the box, papers and extras
The box, warranty card or papers, receipts, manuals, spare links, extra straps and service records all support the watch's history and appeal. A complete "full set" usually attracts more buyers for collectible brands. Cover personal details on receipts before photographing them.
Step 6: photograph it
- The dial straight on, in soft light, without reflections.
- The case from both sides, the crown and the lugs.
- The caseback, with its engravings.
- The bracelet or strap and the clasp, showing its markings.
- The box, papers and extras, plus close-ups of any scratches or damage.
Hide the full serial number in public photos; share it privately with a serious buyer if needed.
Step 7: research the value
Similar-looking watches can sell very differently by reference, dial variant and condition. Scan the watch with WorthAI to identify the likely brand and model and see an estimated worth with a range, a suggested asking price, a reading of buyer demand and the marketplace listings it found. Add a photo of the caseback if it asks, or tap Refine Result. WorthAI cannot authenticate a watch or check the movement, so treat the result as research. Then check recent sold prices for the same reference, with or without box and papers, in similar condition.
Step 8: choose where to sell
- General marketplaces: a wide audience, with authentication programs for higher-value watches on some platforms.
- Watch dealers and jewelers: quick offers in person, usually for less than a private sale.
- Consignment and auction houses: for valuable and collectible watches.
- Watch forums and collector groups: knowledgeable buyers, but check their rules and payment protection.
- Local selling: fine for everyday watches; take extra care with valuable ones.
Step 9: write the listing
Put the brand, model, reference number, case size and dial color in the title. Our listing title builder helps. In the description, cover how well it keeps time, the last service if known, condition, wrist size of the bracelet and exactly what is included.
Step 10: price it and count the fees
Price from recent sales of the same reference and set. Use the resale profit calculator to compare your take-home through a marketplace, a dealer and consignment.
Step 11: ship or meet safely
Wrap the watch, put it in its box, and pack that box in a sturdy shipping box with padding. Use tracking, signature confirmation and insurance that covers the full value. Record a video while you pack. For local sales of valuable watches, meet at a bank or a police safe exchange zone and verify payment before handing the watch over.
After the sale
Keep your photos, packing video and tracking until the sale is final, and transfer any warranty registration if the brand allows it.
Frequently asked questions
Do I need the box and papers to sell a watch?
No, but for collectible brands a full set with box and papers usually attracts more buyers. Without them, clear photos, the reference number and service records still help.
Should I polish my watch before selling it?
Usually not. Collectors often prefer original, unpolished cases, and polishing cannot be undone. Wipe it clean with a soft cloth instead.
How do I find my watch's reference number?
Check the caseback, the space between the lugs, the warranty card and the box label. Some brands also list it in their papers or online support pages.
