Embodiment Construction

[0013] The invention stems from the general innovative idea of ​​using one and / or the other of the upper and lower surfaces of the dial made of non-conductive material to construct conductive paths for connecting the working devices of the watch. discrete or integrated electronic components required. Thus, it is possible to omit or at least limit the surface of the printed circuit board, which makes it possible to limit production time and costs, and to reduce the space required to house the timepiece movement inside the case.

[0014] The invention will be described in connection with a timepiece comprising a crystal on the lower surface of which tactile keys are constructed. Of course, this example is given by way of non-limiting illustration only, and the dial according to the invention can be used with any type of electronic device integrated in a watch case.

Abstract

The invention relates to an electromechanical or digital watch, the watch (1) including a middle (2) which defines, together with a glass (4), a watch case (6), the glass (4) including an upper surface (8) which faces towards a user, and a lower surface (10) which faces the watch case (6), the watch (1) also including a dial (18; 36) made of an electrically non-conductive material, the dial (18; 36) including a lower surface (28) and an upper surface (30) located on the observer side, the watch being characterised in that electrically conductive tracks (26; 40) for connecting one or more electronic components (16, 22) are structured on at least one of the lower (28) or upper (30) surfaces of the dial (18; 36). The invention also discloses a method for manufacturing such a dial.

Description

technical field [0001] The invention relates to a watch comprising a dial. More specifically, the invention relates to an electromechanical or digital watch comprising at least one electronic device arranged within a watch case. [0002] In the sense of the invention, an electromechanical watch is a watch comprising at least one indicator of a time-related or time-independent quantity driven by an electric motor. Furthermore, a digital watch means a watch comprising at least one digital means for displaying a time-dependent quantity or a time-independent quantity. [0003] Likewise, in the sense of the invention, a dial is an indicator part with various time-related or time-independent indications. Background technique [0004] Electromechanical watches, such as digital watches, include a number of discrete or integrated electronic components necessary for the operation of the watch. These electronic components are usually mounted on a printed circuit board located below ...
