Problems solved by technology

Joining the dial in the movement plate according to the aforementioned method has the disadvantage of involving a relatively complex machining operation in which the dial has to be perforated precisely several times before the metal feet are assembled
In addition, there is a risk of breaking the feet of the dial in the event of a significant impact
Also, using such a dial in a skeleton watch is not very aesthetically pleasing

Embodiment Construction

[0022] In general, the device for connecting dials according to the invention according to the different embodiments described below can be implemented in a mechanical or quartz watch comprising a traditional / classical type of dial, ie a dial such as Comprising graduations at regular intervals around the perimeter of the dial, numerals representing the hours, for example in the form of appliqués attached to the dial, and one or more apertures, depending on the movement, to indicate, for example, the date or other information. A dial attachment device according to the invention can also be implemented in watches comprising a dial of an unconventional type. The attachment device according to the invention is, for example, particularly suitable for connecting a dial comprising or formed by a solar cell, which for example powers the accumulator and / or the electronic module of a so-called smart watch.

Abstract

The invention relates to a timepiece comprising a drive module (10), a dial (12) comprising a central opening (13), an hours wheel (14) passing through the central opening (13) of the dial (12) and rotationally driven by the drive module (10), and a dial attachment device. The attachment device comprises a retaining tube (15) arranged around the hours wheel (14) and mechanically connected to the drive module (10). The retaining tube (15) is configured to come to bear against the dial (12) or against a dial support (17) to which the dial is fixed.

Description

technical field [0001] The present invention relates to the field of timepieces and, more particularly, to a timepiece comprising attachment means for attaching a dial of the conventional type or of a type incorporating a solar cell. Background technique [0002] Traditionally, the dial of a timepiece comprises, on the side of the lower face, ie on the side of the movement, metal feet arranged to be partially pressed into holes machined in the plate of the movement. These metal feet are specifically used to hold the dial in place relative to the watch's movement during assembly. Joining the dial in the movement plate according to the aforementioned method has the disadvantage of involving relatively complex machining operations in which the dial must be perforated several times precisely before the metal feet are assembled. In addition, there is a risk of breaking the feet of the dial in the event of a significant impact. Also, using such a dial in a skeleton watch is not ...
