Abstract:
The invention relates to a method which comprises the steps of providing a plate (2) made of a micromachinable material, forming the timepiece component (1) with at least one attachment (3) for keeping the component attached to the rest of the plate (2), by etching the plate (2); and creating, along a desired breakage line of the attachment, a pre-detachment area (4) comprising at least one gap (5) obtained by etching into the body of the plate (2).
Abstract:
A method for determining an imbalance characteristic of a hairspring (5) balance (4) oscillator (3) of a timepiece movement (2), the method comprising at least the following steps: - Setting the hairspring balance oscillator in an oscillating motion at at least two amplitudes, - Determining, for each amplitude and for at least two positions of the oscillator, a piece of data representative of the oscillation period of the oscillator, - Using the data from the previous step to calculate the imbalance characteristic of the hairspring balance oscillator.
