Free Watch Tools

A growing set of free tools for watch owners and buyers β€” work out the right case size for your wrist, or generate everything you need to report and recover a lost or stolen watch. No sign-up, and they work for any brand.

Buying or own a watch? Protect it in seconds.

Check a serial number against our global stolen-watch database before you buy, or register your watch so it's protected if it's ever lost or stolen.

Why we build these tools

StolenWatch runs a global stolen-watch database used by owners, dealers and law enforcement. These free tools help at every stage of owning a watch β€” from choosing the right size to acting fast if one is ever lost or stolen β€” and connect naturally to checking a serial number or registering a watch for protection.

Frequently asked questions

Are these watch tools free?

Yes. Every tool here is completely free and needs no sign-up. The watch size calculator and the lost or stolen watch report generator both run in your browser and work for any brand, including Rolex, Omega, Patek Philippe and Cartier.

Do I need an account to use them?

No account is required. You can use the watch size calculator and the stolen-watch report generator straight away, and nothing you enter is uploaded or saved β€” it all stays on your device.

What tools are available?

Right now there are two tool clusters: a Watch Size Calculator that recommends a case diameter, lug-to-lug and strap width for your wrist, and a Lost or Stolen Watch Report Generator that produces police, insurer, marketplace and recovery documents. More tools are on the way.
