Embodiment Construction

[0013] The invention proceeds from the general inventive concept which consists in providing watchmakers with tools which allow them to separate the bottom cover from the case center of a watch case without the possibility of the bottom cover being reassembled on the case center. The cover leaves visible marks on the owner of the table. The invention also relates to a watch case back with a slit, the contour of which is arranged so that, despite great care when the watchmaker separates the bottom cover from the case center of the watch case, if the bottom cover is marked by this removal operation , once the caseback is reassembled on the case center, the marks left by the tools on the caseback are invisible to the owner of the watch.

[0014] Such as Figure 2A As shown in , the tool 20 according to the invention has the appearance of a wedge, i.e. an acutely angled part formed by a first face 20a and a second face 20b formed at an angle α smaller than 90° intersect and are ...

Abstract

A tool for separating a bottom cover from the center of a timepiece case, a bottom cover having a slot adapted to receive the tool, and a timepiece equipped with such a bottom cover. The invention relates to a timepiece and to a tool intended to be used by a timekeeper to separate a bottom cover from the center of a case, the tool having a wedge appearance, i.e. An acute-angle-shaped part formed by a first face and a second face which intersect at an angle of less than 90 DEG and are connected to each other by a rounded portion, the bottom cover of the timepiece is delimited externally by a periphery, at least one point of which is provided with a slit that releases a space allowing a timekeeper to engage the end of the tool, a lever action being applied on the bottom cover by means of the tool in order to separate the bottom cover from the center of the case, the seam includes a surface inclined at an acute angle with respect to the mean plane when the bottom cover is secured to the case center, the inclined surface extending away from the case center towards its bottom and being extended by a rounded portion that facilitates a connection between the inclined surface and the bottom surface of the bottom cover.

Description

technical field [0001] The present invention relates to a tool intended to assist a watchmaker in separating a caseback from the center of a timepiece case, a caseback having a slot adapted to receive the tool, and a timepiece equipped with such a caseback count. Background technique [0002] When the watch is returned to the factory (for example, for maintenance or repair), the bottom cover of the watch must be opened. However, the operation involving opening the caseback is always delicate and requires great care from the watchmaker making such an intervention. The class of bottom covers to which the invention relates includes bottom covers mounted on the case center by interlocking with a gasket insert between the case back and the case center. In order to allow the caseback to be opened, such a caseback usually has a seam at a point on its outer peripheral edge which allows the watchmaker to insert a tool between the caseback and the center of the case to which it is a...
