FREE Timegrapher App vs. 6 Movements: How Accurate is Your Watch?

Is your mechanical watch running fast or slow? You don’t need a Weishi No. 1000 to get a professional reading. In today’s video, we put a FREE timegrapher app to the ultimate test by measuring 6 different watch movements—from affordable Seiko workhorses to high-beat Swiss calibers.
​We’ll show you how to turn your smartphone into a precision watch accuracy meter to measure:
• ​Rate (Seconds/Day): How much time your watch gains or loses.
• ​Amplitude: The health of your mainspring and balance wheel.
• ​Beat Error: How "in beat" your movement's heart is.

TOOLS USED IN THIS VIDEO:
• ​App: Watch Accuracy Meter (Available on Android/iOS)
• ​Microphone: Standard phone mic

​💡 TIPS FOR THE BEST RESULTS:
• ​Silence is Golden: These apps rely on the phone's microphone. Find the quietest room in your house.
• ​Placement Matters: Remove your phone case and place the watch’s crown directly against the microphone port.
• ​Lift Angle: I test each watch in 2 positions...first Flat then with the 12 o'clock position down to reflect walking/sitting at desk
