Before you buy, sell or insure a watch, you want a fair number. This free vintage watch value calculator starts from real sold prices for 66 popular models, from the Seiko 6309 Turtle and 6139 Pogue to Omega Constellations and the Rolex Datejust. It then adjusts for condition, originality, service and box and papers.

How the calculator works
- Base price. Each model has a range for a running, original watch in very good condition. Where we can, it comes from recent eBay sold data. Otherwise it comes from published price guides, and the result shows a confidence label so you know which one you are looking at.
- Condition. From unworn to for-parts, each grade moves the price. An excellent watch is worth about 19 percent more than a very good one, and a well-worn one about a third less.
- Originality. A refinished dial, replaced hands, a polished case or swapped movement parts each take value off. The losses are multiplied, not added, with a floor, because a watch with many changes ends up in the project-watch market.
- Extras. Box and papers, a recent service with a receipt and the original bracelet all add value, more on expensive watches than on cheap ones.
What the numbers do not include
Rare dial variants, military or celebrity provenance and limited editions can sell far above any average. On the other hand, a watch that looks right but has the wrong caseback numbers is worth much less. That is why the calculator links straight to the Seiko Franken Checker for any vintage Seiko it knows the reference for. For a visual check, see the franken gallery, and take the free buying checklist with you.

Frequently asked questions
How much is my vintage Seiko worth?
It depends on the reference first, then on originality and condition. A running, original 6309 Turtle typically sells for about $400 to $650, a 6139 Pogue for $450 to $800 and a 6105-8110 for $1,800 to $3,200. A refinished dial or swapped parts can cut those numbers by half or more.
Is this calculator an appraisal?
No. It is an estimate built from published sold prices and value guides. For insurance or a sale over a few thousand dollars, get the watch inspected and appraised in person.
Why is the dealer price lower than the estimate?
A dealer has to check, service, photograph and guarantee the watch, then wait for a buyer. Valuation guides put typical dealer offers at 50 to 70 percent of resale value.
Do box and papers really add value?
On luxury brands, yes: a full set usually adds 10 to 20 percent. On a vintage Seiko 5 or a Timex the premium is small, because few buyers pay extra for paperwork on a $100 watch.
What hurts the value of a vintage watch the most?
A refinished dial. Restoration guides put the loss at 40 to 80 percent. After that come a heavily polished case, replaced hands and parts from another movement.
My watch is not on the list. Can I still use it?
Yes. Choose ‘My watch is not listed’ and enter either a recent sold price for the same model, or the retail price when new for brands such as Rolex, Omega, Tudor, Grand Seiko, Cartier, Breitling and TAG Heuer.
