Description by Louis Marion Written by the developer, not by AppBrain. Click to read.
Precision Watch measures your watch's true daily accuracy by comparing it to atomic time — no expensive timegrapher and no trip to the watchmaker. Start a measurement, come back later, enter what your watch reads, and see exactly how many seconds per day your watch gains or loses.
WHY PRECISION WATCH
• Atomic-accurate — every measurement is referenced against an atomic clock
• No microphone guesswork — a reliable, repeatable method that actually works
• Track every watch — build your collection and follow each one's rate over time
• Fast & beautiful — a clean, native experience made for watch lovers
• Private — everything stays on your device, no account required
HOW IT WORKS
1. Sync your watch to the on-screen atomic clock
2. Wait — from a few minutes to several hours, your choice
3. Enter what your watch reads now
4. Get your precise +/- seconds-per-day result
Know when your watch truly needs a service — and when it doesn't. Stop guessing and start measuring.
Precision Watch Pro unlocks unlimited saved measurements and your full watch collection.
