How ONEOF Acoustic Sensors Work

In a mechanical watch, the energy is transmitted from the escapement to the balance wheel mainly by parts that slide or are pushed, making the well known “ticking” or “tick-tock” sound.

ONEOF products are made up of an ultra sensitive sensor which is capable of detecting every single vibration caused by the ticking sound. Each of these small vibrations is converted into an audio signal and then highly amplified, digitalized and transmitted to the device, where all the gathered data is analyzed and interpreted in an easy-to-read user interface.

Accaracy2 and Accuracy App - How ONEOF Acoustic Sensors Work

The ticking sound of the Swiss lever escapement consists of 3 different pulses. The first pulse is temporally very precise and therefore it is used for the computation of the rate deviation and the beat error. A second pulse is very irregular and cannot be used. The third and most powerful pulse is used to estimate the amplitude of the balance wheel.
