Estimate the accuracy of mechanical watches using the phone microphone

Features & Capabilities

Watch Accuracy Meter is a Chrome extension designed to estimate the accuracy of mechanical watches using your phone's microphone. Within just 60 seconds, it provides key watch metrics such as beats per hour, rate in seconds per day, beat error (ms), and amplitude — all crucial for watch enthusiasts and professionals.

The extension requires no external hardware and includes multiple measurement screens and detection algorithms. It can function effectively even with some background noise. Users can adjust settings like beats per hour and lift angle and save and compare multiple results. Note that measurements may vary depending on watch position and power reserve, and the estimations are meant for watches, not clocks, with a disclaimer that actual values might differ.

User Reviews

Watch Accuracy Meter is a popular free Android tool for quick watch timing checks. Users praise its accessibility, ease of use, and reasonably accurate readings for routine checks, with trace viewing and data recording. However, reliability concerns persist: accuracy lags behind professional timegrapher results; updates can introduce bugs; data management and UI issues occur on some devices; and readings depend on microphone quality and placement. It’s a strong free option for quick checks but not a substitute for professional instrumentation.

Pros

Free and ad-free, making it accessible for everyone.
Easy to use for quick watch timing checks.
Reasonably accurate readings for quick estimates, especially for the price.
Allows viewing the trace and recording data for later review.
Useful without heavy equipment; external mic can improve readings.

Cons

Not as accurate as a professional timegrapher; should be used for quick checks only.
Bugs and instability after updates, including missing rate/beat‑error or amplitude values.
Data management issues: traces may not save, and import/export/delete features can fail.
UI/resolution and device compatibility problems in some devices.
Readings are sensitive to microphone placement and hardware; case removal or external mic can be required for better results.

S25ultra works well. My s23 does not. My biggest issue is with my S25 my Navigation bar at the bottom which is non negotiable, does not allow me to pick the import, export functions of the app. I can see them in the background behind my screen nav functions but cannot select them. Otherwise it did a great job regulating my new Seiko SNKM97 RECRAFT. it was like 23 sec slow out of the box. messed with it for a long time in different positions to get something avg out to a plus net. pretty pleased

Works exactly as expected. The only thing I wish is added is a rate measurement over the whole interval that has at least one more digit of accuracy. This rounding makes it impossible calibrate watches to within a few seconds because of the large rounding error.
