Embodiment Construction

[0025] The invention proceeds from the general inventive idea of ​​providing a fastening system that allows fixing the horological movement of a watch relative to the case lining. Thus, in the event of a shock to the watch, any relative movement of the timepiece movement with respect to the case lining and the case is prevented, thereby avoiding any risk of damage to components such as the winding shaft mechanically connected to the timepiece movement or correction axis. The invention is of particular interest for many horological movements which are still fastened in the lower part of the case lining by means of two screws placed on opposite sides of the diameter of the horological movement at the ends and define an axis about which the timepiece movement is able to pivot in the event of a shock to the watch. Rather than rethinking the arrangement of the timepiece movement, which entails costs, the present invention teaches the use of a third fastening device, such as a scre...

Abstract

A fastening system for fastening a timepiece movement in a watch case. The invention relates to a fastening system for fastening a timepiece movement (2) of a substantially circular shape in a case (20), comprising a case collar (1) in which said timepiece movement (2) is arranged, the case collar (1) extending between an upper part and a lower part, the timepiece movement (2) is fastened in the lower part of the case collar (1) using first and second fastening means provided at two opposite ends of the diameter (D) of the timepiece movement (2), at least third fastening means being angularly offset and fastened in the upper part of the case collar (1) with respect to the first and second fastening means, this allows the timepiece movement (2) to be blocked in the case collar (1).

Description

technical field [0001] The invention relates to a fastening system for fastening a timepiece movement in a watch case. More specifically, the invention relates to a system that allows the fixation of a timepiece movement arranged in a case lining provided in the case of a watch. Background technique [0002] A timepiece (especially a wristwatch) usually includes a centerpiece closed at the bottom by a caseback. These two elements (centre piece and case back) together form the case that defines the internal volume in which the timepiece movement (also known as the calibre) is housed. Towards the top, the case houses a dial protected by a glass. [0003] Such a horological movement is arranged in the inner volume of the case either directly or by means of a case lining in which the horological movement is embedded, as the case may be, the assembly formed by the horological movement and the case lining It is then housed in the watch case. [0004] The fixation of the timepi...
