EPHJ Grand Prix 2017

for the WisioScope Product


Laser shines on mechanical watchmaking
A joint development from Witschi and CSEM for the EPHJ trade fair.


The exhibitors at this event for high-precision solutions are rewarding the WisioScope product, by Witschi, with their Grand Prix 2017. The jury was convinced by the unique and innovative nature of this development, intended to enable the calibration of mechanical watch movements, which are ever more sophisticated and quiet.

While watchmakers typically fine-tune movements by monitoring their ticking, Witschi had the idea of measuring these “silent oscillators”. To create a product from this concept, they worked with CSEM in a partnership that was supported by the CTI. The fruit of this successful collaboration – the WisioScope S – monitors oscillator amplitude and frequency with photodetectors that measure the flicker of laser light reflected off the balance wheel.
