WatchRadar blog

Watch authentication, in long form.

In-depth posts on watch authentication, pre-purchase inspection, the secondary market, and how WatchRadar approaches each. Written by people who use the app on real watches, and updated when the facts change rather than on a content calendar.

Where to start

If you are about to buy a specific watch, go straight to the brand tells: the fake Rolex Submariner walkthrough or the Royal Oak equivalent. If you are buying from a marketplace listing, read the Chrono24 verification checklist first and the eight seller questions second. If you are deciding whether an app is the right tool at all, the services comparison is the honest version, and WatchRadar vs Entrupy goes deeper on the single closest alternative.

The brand-by-brand reference material lives outside the blog, in the authentication guides — one page per maker, covering the specific tells the on-device model grades for Rolex, Audemars Piguet, Patek Philippe, Omega, Cartier and Jaeger-LeCoultre.

A note on what we will not publish

No post here guarantees that a watch is genuine, and none is a substitute for a watchmaker opening a caseback on a high-value purchase. Where a claim is brand-documented — a certification scheme, a warranty format change, a reference transition — it is stated as such; where it is a pattern we observe in scans, it is described that way. Counterfeit quality moves, so posts get corrected rather than quietly left to age.
