Abstract
A method for frequency tuning a set of plates of a watch. The plates are disposed one above the other forming a watch dial with a space defined between the plates. A mechanical shock to the set of plates is generated, and the vibration frequency of each plate is checked. The vibration frequency of at least one of the plates is matched if different from the other plate so as to obtain an identical vibration frequency for each plate in order to tune the plates at least according to the first vibration eigenmode so as to avoid any contact between the plates as a result of any mechanical shock.

A method for frequency tuning a set of plates of a watch, the plates being disposed on top of one another with a space defined between the plates, and wherein the set of plates forms a dial of the watch, with at least a first dial plate and a second plate on top of and spaced apart from the first plate, the method comprising:
- checking a vibration frequency of each plate after a mechanical shock is generated to the set of plates;
- matching the vibration frequency of at least one plate of the set of plates according to a vibration eigenmode if the vibration frequency of the at least one plate is different from the vibration frequency of another plate of the set of plates;
- and
- obtaining a match vibration frequency for each plate according to the vibration eigenmode for tuning the plates to avoid any contact between the plates as a result of the mechanical shock.
