This paper presents a new mechanical regulator for wrist watches, highlighting the methodology used to set up a comprehensive model of the device. The mechanical regulator, which is characterized by a high frequency monolithic oscillator made of monocrystalline silicon coupled to a deadbeat escapement, has been designed to provide a high quality factor, a condition necessary to guarantee enhanced chronometric performances compared to traditional mechanical regulators. The chronometric performances and the isochronism of the oscillating system have been assessed by means of a multi-body model whose parameters have been evaluated by FE and CFD simulations.

Abstract

This paper presents a new mechanical regulator for wrist watches, highlighting the methodology used to set up a comprehensive model of the device. The mechanical regulator, which is characterized by a high frequency monolithic oscillator made of monocrystalline silicon coupled to a deadbeat escapement, has been designed to provide a high quality factor, a condition necessary to guarantee enhanced chronometric performances compared to traditional mechanical regulators. The chronometric performances and the isochronism of the oscillating system have been assessed by means of a multi-body model whose parameters have been evaluated by FE and CFD simulations.
