Problems solved by technology

The structure of the watch case must be changed when one wants to replace the electronic module, causing cost and production line flexibility issues
[0005] Furthermore, the fastening system provided in the case is not entirely satisfactory, some parts such as the battery are not sufficiently fastened
[0006] It has also been observed that when the battery is replaced, the electronic modules are largely exposed, which can lead to a deterioration in their quality, affecting the reliability of the timepiece

Embodiment Construction

[0034] In the following description, an orthogonal coordinate (where V, L, T denote vertical V, longitudinal L and transverse T directions, respectively) is used in a non-limiting sense. Similar or identical parts are denoted by the same reference numerals.

[0035] 1-8 illustrate the constituent elements of an electronic timepiece 10 in the form of a wristwatch made in accordance with the teachings of the present invention.

[0036] Timepiece 10 includes a watch case 12 housing a first electronic module 14 and a second electronic module 16 electrically connected to each other and powered by a battery 18 . The electronic modules 14, 16 are stacked along a vertical axis A1.

[0037] In the following description, the axial orientation along the vertical axis A1 is used in a non-limiting sense.

[0038] The watch case 12 consists of a generally circular middle part 20 closed at its top by a protective crystal 22 placed above a display device 24 and at its bottom by a glass atta...

Abstract

The electronic timepiece ( 10 ) includes a case ( 12 ) that contains at least one first and one second electronic module ( 14, 16 ) powered by a battery ( 18 ). The case ( 12 ) is formed by a middle part ( 20 ), which is closed by a protective crystal ( 22 ) placed above a display device ( 24 ) and by a cover ( 26 ) added to the case ( 12 ). The case ( 12 ) includes an added partition ( 32 ), which is secured to the middle part ( 20 ) and which delimits a top compartment ( 34 ) containing the first electronic module ( 14 ) and a bottom compartment ( 36 ) containing the second electronic module ( 16 ). The battery ( 18 ) is arranged in a complementary housing arranged in the bottom face ( 40 ) of the partition ( 32 ). A method of assembling the timepiece ( 10 ) is also provided.

Description

technical field [0001] The invention relates to an electronic timepiece and an assembly method thereof. [0002] In particular, the present invention relates to an electronic timepiece comprising a watch case containing at least a first electronic module and a second electronic module electrically connected to each other and powered by a battery, wherein the watch case is separated by an intermediate The middle part is formed by a part closed at its top by a protective crystal placed above a display device and at its bottom by a cover attached to the watch case. Background technique [0003] US Patent No. 2005 / 0253047 discloses and shows a timepiece constituted by a wristwatch including timing functions such as time display and auxiliary functions of time display constituted by the pulse measurement function of the wearer of the watch. The chronograph functions and watch display control are handled by electronic circuits arranged on a top printed circuit board secured in th...
