H2i, Petitpierre and Horlyne to take part in the Technical Watchmaker Show 2023
view moreAcoustic measurement has been widely used in the watchmaking industry for years as a simple and reliable way of verifying a watch's precision and detecting defects in the ticking signal.Because the needs of different clients vary, relying on a user-centric approach we have developed the ONEOF® line of products as a range of dedicated, powerful and contemporary timing instruments.
The Accuracy Pro and Accuracy Motion are respectively manual and motorized multiposition watch timing devices dedicated to professional watchmakers. Powered with our latest high-precision technology and linked to the ONEOF® apps, they offer an outstanding user experience.
Our success has been built on two breakthrough products which are still unique in their field to this day. The ONEOF® Accuracy2, the smallest watch measuring tool ever built, and the ONEOF® Accuracy Boutique Edition, the only acoustic instrument capable of measuring and demagnetizing a watch simultaneously.
