The Valjoux 7750 was the first ever mechanical movement to be designed on a computer. The young watchmaker in charge, Edmond Capt, wanted to use Valjoux know-how to create a movement that would be straightforward to manufacture and to regulate. It is still in production after 47 years, and it has become a staple of Swiss watchmaking.
For our Siduna M3440 Compax and Fly-back chronographs, we use the Top Grade, which receives an Incabloc shock protection, a Glucydur balance wheel (same as the Chonometer Grade and more resilient to temperature change and shocks) and an Anchron Nivaflex NM hairspring. The bridges and rotor are decorated with Geneva stripes, which are designed to catch and hold specs of dust until the next servicing.
