Accuracy2

The new measurement tool for mechanical watch lovers.

- Dragonfly Technology. Every sound counts.
 
Accuracy2 is made of an ultra sensitive sensor which is    capable of detecting every single vibration in the movement   of a mechanical watch. Each of these small vibrations is    converted into an audio signal, highly amplified,    digitalized and transmitted to the device where every    second, complex algorithms process tens of thousands of    data.

- A step ahead, once again.

While other connected measurement tools on the market work only with the analog and disappearing audio jack connector, ONEOF engineers clearly anticipated and developed a brand new digital audio electronic system based on the commonly used USB standard.


- Measure your watch in a split-second.

The new Accuracy app developed by our engineers automatically detects the presence of your watch on the sensor. Just after a few seconds of initialization, you get all the detailed technical information you need in a professional and user-friendly app.


- Magnetization: the main watch illness.

Strong magnetic fields are everywhere, generated by commonly used objects such as speakers, motors, electronic devices and even leather goods. Only few brands are able to propose watch movements insensitive to magnetic fields. The main symptoms of a magnetized watch are generally a low amplitude of the balance wheel and, more critically, an important loss of precision up to minutes per day.


- Scan your watch.

The new Accuracy app uses the integrated magnetic fields sensor of your device in order to check whether your movement is magnetized. Scan your watch on every angle and see if it suffers from magnetization.
