Download APK Android 8 or later · Installation from unknown sources must be enabled in your device settingsImportant note: The AI-powered watch check serves only as an initial assessment and does not replace a professional appraisal by an expert. ChronoCheck accepts no liability for decisions made based on this analysis. The AI analysis is not a legally binding appraisal.
You photograph the dial, movement and serial number. The ChronoCheck AI compares over 50 features against a database of originals and known counterfeit patterns and delivers a verdict with reasoning within seconds.
The download and the first checks are free. For unlimited AI analyses, market-value data and the watchlist there is an optional premium subscription. A pre-check before a purchase costs a one-time €14.99.
The focus is on the most counterfeited luxury brands: Rolex, Audemars Piguet, Patek Philippe, Omega, Hublot, IWC, Breitling, Cartier and Panerai. More brands are added on an ongoing basis.
The AI is built as a first indicator: very reliable for clear fakes, and for borderline cases it returns an "uncertain" result and recommends an expert review. For legally binding statements there is the CPS-52 certificate.
The app check is AI-powered and delivers an indication within seconds. The CPS-52 inspection is a 52-point procedure carried out by certified experts — including movement inspection and a PDF certificate with a blockchain hash. Recommended for high-value sales.
You decide for yourself. By default, photos are processed locally and are not made public. You can optionally share analyses with the community, though — for example, to help train the AI further and collect points in the Watch Game.
