The Wittnauer C11KS watch movement, which was produced from 1959 onwards, features an excenter regulator for the stud carrier. This movement incorporates an intermediate wheel situated between the minute pinion and the rest of the train, enabling a sizable balance and a low profile while maintaining robustness. Furthermore, this layout allows for the seconds wheel to be positioned either in the center or as a sub second without necessitating additional modifications. The movement operates via manual winding and includes a sub second function.
