What makes CH calibers so special?

All calibers from our long-standing raw movement suppliers are delivered as Ebauche or completely dismantled and refined in Germany before they are installed in one of our watches.
To this end, all parts undergo a complex QA process before they are revised, e.g. B. finished or chamfered. Sometimes entire components are replaced or improved - e.g. For example, shafts are polished, entire groups of escapements are exchanged, and stronger springs are used in order to maximize accuracy, smooth running and reliability. As a result, most movements from the CH line are equipped with 28,800 A/h vibrations per hour.

After encasing the calibers in our watches, the CH calibers are tested again for function and finely adjusted in all positions on an electronic timegrapher in order to achieve chronometer values in the best case.

All our watches with Swiss calibers come with a five-year guarantee.
