Abstract
The invention relates to a timepiece assortment including a timepiece component fixed to an arbor with the aid of a fixing element. According to the invention, the fixing element is made of at least partially amorphous metal alloy, is secured to the timepiece component by partial insertion and includes a hole into which the arbor is driven.
Claims25
A timepiece assortment that is assembled by the following steps:
- a) separately manufacturing a timepiece component and a fixing element, the fixing element being manufactured from an at least partially amorphous metal alloy;
- b) partially inserting at least one portion of the timepiece component into a thickness of the fixing element heated to between its vitreous transition temperature and its crystallization temperature in order to form a timepiece component fixing element assembly;
- c) driving an arbor into a hole of the fixing element to form the timepiece assortment so as to leave a gap between timepiece component and the arbor,
- the timepiece assortment comprising:
- the timepiece component fixed to the arbor with the aid of the fixing element including the hole into which the arbor is driven, wherein the fixing element is secured to the timepiece component by partial insertion of one into the other, and wherein the timepiece component includes an opening which extends around the hole of the fixing element and has a larger cross-section so that the gap is between a wall of the opening and the arbor.

A timepiece assortment that is assembled by the following steps:
- a) separately manufacturing a timepiece component, a fixing element made of an at least partially amorphous metal alloy and a driving-in member provided with a hole;
- b) partially inserting at least one portion of the timepiece component and of the driving-in member into a thickness of the fixing element heated to between its vitreous transition temperature and its crystallization temperature to form a timepiece component fixing element driving-in member assembly;
- and
- c) driving an arbor into the hole in the driving-in member to form the timepiece assortment so as to leave a gap between timepiece component and the arbor,
- the timepiece assortment comprising:
- the timepiece component fixed to the arbor with the aid of the fixing element and the driving-in member including the hole into which the arbor is driven, wherein the fixing element is respectively secured to the timepiece component and to the driving-in member by partial insertion of one into the other, and wherein the timepiece component includes an opening which extends around the hole in the driving-in member and has a larger cross-section so that the gap is between a wall of the opening and the arbor.
