Additional information from Peter Chong: The base movement is a 7750. But the entire chrono works is inhouse (by
Jacquet…who is another partner in Les Mont), and features two column wheels because it features a split seconds chronograph. This is the traditional rattrapante
design…utilising one column wheel for the base chrono function, and another for the split seconds work. |
