Manufacture

The manufacturing process starts in the “ebauche” workshop, where the main components of the would-be movement are machined using digitally controlled machining units.

After rough machining, each part undergoes processing. Holes are bored or ground down, to enable highly precise adjustments, and diamond polishing operations are carried out in order to prepare surfaces for the requirements of the finishing operations.

Within the Girard-Perregaux Manufacture, machining is also used for modelling watch cases. After these operations, the middle parts are entrusted to the polishing workshop to give them their final appearance and finish, through patient manual work. The various constituent parts of the watch case (bezel, crystal, gaskets, etc.) can then be assembled to form the case.
