H2i, Petitpierre and Horlyne to take part in the Technical Watchmaker Show 2023
view moreThe ONEOF Accuracy2 is a compact and powerful acoustic measurement device for testing the accuacy of your mechanical watch.
The ONEOF Accuracy2 uses 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 and then highly amplified, digitalized and transmitted to the mobile app. In the app, the data is gathered, analysed and interpreted through an easy-to-read graphical interface.
While other connected measurement tools on the market work only with the analog and disappearing audio jack connector, ONEOF engineers developed a brand new digital audio electronic system based on the commonly used USB standard.
The jack connector with analog audio is outdated. The 16 bits / 48KHz digital audio used in ONEOF Accuracy2 gives better measurement performance than any other product available on the market.
The ONEOF accuracy2 is a stand-alone device. It requires no battery or power supply. Plug it in and forget it, it is that simple.
