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 algorithm process tens of thousands of data.

While other connected measurement tools on the market work only with the analogue 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.
