Complete control. Endless possibilities.
Historically, watchmakers test and adjust the chronometric precision of mechanical movements using acoustic measuring devices in six static positions in order to compensate for the effect of Earth’s gravity on the regulating system.
Six static positions are no longer sufficient because it is simply not representative of the actual wear of a watch which evolves in a dynamic three-dimensional environment with complex and varied disturbances. The ONEOF® Accuracy Motion was developed from this observation and from our desire to offer watch brands a tool that is capable of doing more and doing it better by using the latest adapted technology.
ONEOF® uses OM10 open source movement 3d data
Cutting-edge technology.
Pushing the technological limits of a product requires rethinking the classic engineering from the early stages of its development. By equipping the Accuracy Motion with direct control with an Inertial Measurement Unit and strain wave gears (better known as of Harmonic Drive®), the product is more similar to aerospace technology than to standard watchmaking industry technology.
32’400 dynamic orientations.
The Accuracy Motion can be controlled without any backlash – not only in the six standard static positions, but degree by degree, in 32’400 different orientations (90° x 360°). In addition, it allows speed control ranging from one degree per second to more than fifteen rotations per minute.
These features offer new possibilities for manufacturers who will create new test and control processes as they see fit, thus promoting optimal chronometric quality of their watches before they are put on the market.
Experience a clear workspace.
When using several measuring instruments side by side for production purposes, keeping a clear workspace can get very complicated. All ONEOF® devices work with a single USB cable and support the multi-device plug&play technology.
