Hacking Seconds

Hacking Seconds is a quick reference app for watch enthusiasts. Set any watch accurately with clear displays for GMT, 24-hour time, moonphase, and DST transitions. Includes step-by-step setting guides for popular digital watches.

Track your mechanical watches' accuracy over time and spot regulation drift. Interactive bezels and dials with haptic feedback let you spin dive bezels and adjust GMT complications just like the real thing.

Get notified before DST changes and at the end of short months so your watches stay accurate.
