Moonphase Setter - Watch Sync

Complete the Universe on Your Wrist.

A moonphase watch is at its most beautiful when it shows the moon that's actually in the sky. Moonphase Setter tells you exactly how far to move it, and guides you through every turn or press.

■ How it works
1. Take a photo of your watch dial.
2. Line up the moon on the dial with the target moon, by hand or with AI analysis.
3. Follow the instruction: how many times to turn the crown, press the corrector or pusher, or turn the hands.

■ Step-by-step adjustment guide
• Supports crown, corrector, pusher and hand-rotation movements
• Crown that can turn backward? The shorter direction is suggested
• Tap a counter with each turn or press so you never lose count
• Re-take a photo afterwards to verify the result

■ Protects your movement
Between 9 PM and 3 AM many movements are changing the date or moonphase, and adjusting can strain the gears. The app warns you during this window, in your observation location's time zone.

■ My Watches
• Save each watch with its adjustment method and photo, and start your next sync in a tap
• Re-sync reminders: the app estimates how far each watch has drifted since its last sync, from its gear train, and lets you know when it's about a day off

■ AI watch identification
Not sure how your watch is adjusted? Identify it from your photo, then open its manual to check the moonphase setting.

■ Moon calendar
See a whole month of moons with each new moon, quarter and full moon, and jump to any date.

■ Accurate for where you are
The moon is calculated for your location and time zone. Use GPS or search for any place, with a southern-hemisphere view when you need it.

■ Premium
More daily AI analyses, unlimited watches and no ads. The adjustment guide, danger-time warnings, manual verification and re-sync reminders are always free.

Adjustment methods vary by model and movement; please check your watch manufacturer's manual for details.

Give your timepiece the gift of perfect synchronization.
