Winder: Set Watch Time

Winder helps you manually set your mechanical or luxury watch with atomic-level precision, down to the exact second.

Whether you’re a collector, enthusiast, or just someone who cares about the details, Winder gives you real-time, ±20ms-accurate time thanks to atomic clock sync via NTP.

Choose between a clean digital timer or an elegant analog watch face with smooth animations. Enable optional countdown sounds to help you synchronize your watch with analog beeps or mechanical ticks. You can even customize volume and countdown timing.

No fluff. No ads. Just a refined tool for serious timekeepers.

Winder is completely free and built by the team behind Watchdex, a new collector’s tool for organizing and preserving your collection. If you're passionate about horology, you’ll love what’s coming next.
