H2i, Petitpierre and Horlyne to take part in the Technical Watchmaker Show 2023
view moreThe ONEOF® Accuracy Pro is a high-end multi-position acoustic sensor for the measurement of mechanical watches. This device opened up a new era of innovation in the field of watch measuring instruments.
With our dedicated and powerful acoustic technology, our sensors perfectly meet the most stringent requirements of the Swiss watch industry.
As for all our professional acoustic measuring instruments, the electronic board of the ONEOF® Accuracy Pro is based on the premium XMOS micro-controller, a flawless hi-res USB audio processor.
The ONEOF® Accuracy Pro is made entirely in a high-grade anodized aluminum alloy. All sensitive elements potentially in contact with the external parts of the watch are coated with a soft-touch rubber.
ONEOF® uses OM10 open source movement 3D data
Linked with an Inertial Measurement Unit – a MEMS component that combines an accelerometer and a gyroscope – the device delivers real-time data about both the orientation of the watch and the signal of its escapement.
The Accuracy Pro comes with a newly developed Windows App which integrates all the features you need: realtime scope view, diagram display, dispersion over time, cumulated graphs, tabular and radar chart all in an intuitive and user-friendly interface.
