MoonSet: Moonphase Calibrator

Stop guessing. Get the exact number of presses to sync your moonphase complication perfectly. No ads, no subscriptions—just precision for your mechanical watch.

Stop guessing and start syncing. MoonSet is the dedicated tool for watch collectors to perfectly calibrate their mechanical moonphase complications.

The problem: You haven't worn your watch in a few days. The movement stopped. Now, how many times do you need to press that tiny corrector button to get the moon back in sync?

The solution: MoonSet. We give you the "One Number"—the exact count of actuations needed to match today’s lunar cycle.

HOW IT WORKS

1. Open MoonSet or check your Home Screen Widget.
2. See the number (e.g., "14 days since Full Moon").
3. Use your stylus to press the corrector button that many times. Done. Your watch is perfectly accurate.

DESIGNED FOR WATCH ENTHUSIASTS MoonSet is built for anyone who appreciates mechanical precision. Whether you’re setting a perpetual calendar or a simple lunar sub-dial, our interface replicates the classic dual-moon disk design found on the world’s finest timepieces.

ASTRONOMICAL ACCURACY We don’t just use a generic calendar. MoonSet utilizes high-fidelity astronomical algorithms (Julian Date system) to track the 29.53-day synodic month. • Covers all 8 lunar phases. • Works 100% offline. • Zero server lag.

PLAN YOUR ROTATION Use the built-in 4-year Lunar Calendar to see every upcoming Full Moon. Perfect for knowing exactly when your next "zero-point" window arrives to reset your collection.
