A score you can read, not just trust
Every listing is rated on six things. Some matter more than others, so the total reflects how real buyers weigh them.
When a listing doesn't mention box and papers, service history or completeness, we leave them out of the score instead of guessing.
Built around the real decision
- Ideal Offer
- A suggested opening price and a ceiling, based on how the listing scores against similar ones.

Questions
Is this a professional appraisal?
No. WatchCheck gives AI-generated guidance based on the photos and details you provide. It can't inspect a watch in person. For a big purchase, get an in-person inspection or authentication from a qualified watchmaker or dealer.
Which watches does it work for?
Any brand. You describe or photograph the listing, and the app judges the deal in front of you.
What does it cost?
There's a free plan with a monthly scan limit. WatchCheck Pro is an optional subscription with higher limits. Pricing is shown in the app before you buy.
What happens to my photos?
They're stored privately in your account and sent only to our AI provider to analyze your request. We don't sell your information. You can delete a listing or your whole account from inside the app. Read the Privacy Policy.
Is there an Android version?
Not yet. WatchCheck is an iPhone app for now.
