Sonnerie Souveraine

As technically complex as it is simple to use without any risk of damaging it, this striking watch represents the culmination of research that aimed in particular to minimise the use of energy while maximising its mechanical efficiency. A single spring supplies enough energy for 24 hours in the “grand strike” mode (corresponding to 96 full chimes), the minute repeater and 48 hours of running. If the striking mechanism is not used, the movement has a full five-day autonomy. No less than ten patents have been filed for this achievement that took a full five years to development. The dial displays the hour and minute at 3 o’clock, small seconds at 6 o’clock, a power reserve, striking mode selection and a window revealing the striking hammers.
