Method for frequency tuning a set of plates of a watch, and watch comprising the set of tuned plates

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 a...

Zusammenfassung:	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.
