Embodiment Construction

[0020] figure 1 and figure 2 A watch 2 including a bracelet 4 and a case 6 is shown. Without being so limited in the context of the present invention and for a better understanding of the present invention, the watch in this context is an electronic watch 2 such as a quartz watch.

[0021] In this context, the watch case 6 then comprises in a conventional manner at least one electrical or electronic element 8a-8g. In a non-limiting and non-exhaustive manner, the watch case 6 includes seven electrical or electronic elements 8 a - 8 g that constitute the sensitive part of the watch 2 . Of course, the watch case 6 may include more electrical or electronic elements than those shown in these figures, or may include only a subset of the elements of the components 8a-8g. In these variants, the watch case 6 thus comprises, for example, a display device 8a, a processor 8b, a memory 8c, an energy storage means 8d, an electric motor 8e, an integrated circuit 8f and an electronic osci...

Abstract

The invention relates to a watch (2) according to the previous claim, characterized in that it comprises a bracelet (4) and a watch case (6), said watch case (6) comprising at least one electrical or electronic component (8a-8 g), said watch comprising at least one Dewar device (10) configured to enclose at least one of said electrical or electronic components (8a-8 g), the at least one Dewar device (10) comprises inner and outer walls (12a, 12b) and a vacuum or quasi-vacuum space (16) defined between these walls (12a, 12b), the inner wall (12a) delimiting a volume (14) in which the at least one electrical or electronic component (8a-8 g) is adapted to be arranged, and the outer wall (12a, 12b) delimiting a volume (14) in which the at least one electrical or electronic component (8a-8 g) is adapted to be arranged. The watch (2) comprises an optical filter element (22) defined in all or part of the particularly visible outer surface of the case (6), said optical filter element being able to transmit only the visible electromagnetic spectrum.

Description

technical field [0001] The present invention relates to a watch comprising an optical filter element. Background technique [0002] A watch usually consists of a bracelet and case, with a mechanical movement or even an electronic quartz movement arranged in the case. It is well known that such movements are often very sensitive to temperature changes, which can be the cause of many failures and their reduced storage properties. For example, an increase in temperature can lead to an expansion of the materials that make up, in particular, the hairspring and balance of a mechanical movement. This expansion then changes the stiffness of the spring and the inertia of the balance wheel, causing the frequency of the mechanism to change. In this context, in order to avoid such failures, it is known to use mechanisms for compensating for the effect of these temperature changes on the operation of these movements, which mechanisms are not always very effective. [0003] Understanda...
