ONEOF Accuracy2 – Measurement Tool for Mechanical Watches

Dragonfly Technology – Every Vibration Matters

Accuracy2 features an ultra-sensitive sensor capable of detecting even the smallest vibrations inside a mechanical movement.
Each vibration is converted into an audio signal, amplified, digitized and processed in real time by advanced algorithms within the app.

Fast and Accurate Measurement

The Accuracy app automatically detects the watch placed on the sensor.
After a short initialization, you instantly receive detailed technical measurements in a clear and professional interface.

Magnetization Detection

Magnetic fields are everywhere (speakers, motors, electronic devices, etc.) and can significantly affect watch accuracy.
The app uses your smartphone’s magnetic sensor to check whether your watch is magnetized.
