Accuracy 2 - Acoustic Measurement Device
The ONEOF Accuracy2 is a compact and powerful acoustic measurement device for testing the accuacy of your mechanical watch.

One Step Ahead, Once Again
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.
No jack connector
The jack connector with analog audio is outdated.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.
Plug and Play
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.
