Abstract

A Dewar device for mechanical and/or functional components of a watch, the device being provided with a bracelet and a casing including an enclosure wherein a case of the watch can be disposed so that a crystal of the case is arranged opposite a crystal of all the elements of the casing defining this enclosure and at least one fastening device fastening the watch case in the enclosure of the casing by keeping it remote from all the elements of the casing defining this enclosure, the Dewar device including a device for actuating at least one push button by rotating a pivoting bezel of the casing.

First claim

The invention claimed is:

1. A Dewar device for mechanical and/or functional components of a watch, said device comprising:
a bracelet;
a casing including an enclosure wherein a case of said watch can be disposed so that a crystal of said case is arranged opposite a crystal of said casing;
at least one fastening device fastening said watch case in said enclosure of the casing by keeping it the watch case spaced apart from all elements of the casing defining said enclosures; and
a device for actuating at least one push button by rotating a pivoting bezel of said casing.

2. The Dewar device according to claim 1 , wherein said device for actuating said at least one push button comprises said pivoting bezel which is configured to participate in the actuation of said at least one push button when it the pivoting bezel performs a rotational movement around a central axis of the pivoting bezel.

3. The Dewar device according to claim 1 , wherein said pivoting bezel is movable in rotation relative to a middle of the casing.

4. The Dewar device according to claim 1 , wherein the actuating device comprises the pivoting bezel, a middle of the casing and at least one deformable lever element.

5. The Dewar device according to claim 4 , wherein said at least one lever element comprises a first end fastened to a middle of the casing and a second end fastened to the pivoting bezel.

6. The Dewar device according to claim 4 , wherein said at least one lever element comprises a first end fastened to a middle of the casing and a second end fastened to the pivoting bezel, the at least one lever element comprising first and second parts of different sizes movably connected together by a fastening element.

7. The Dewar device according to claim 4 , wherein said at least one lever element comprises a first end fastened to a middle of the casing and a second end fastened to the pivoting bezel, the at least one lever element comprises connecting elements capable of ensuring a movable fastening of said lever element to the middle and to the bezel of the casing.

8. The Dewar device according to claim 4 , wherein said at least one lever element comprises a first end fastened to a middle of the casing and a second end fastened to the pivoting bezel, the at least one lever element comprising first and second parts of different sizes movably connected together by a fastening element, the first and second parts being interconnected at connecting ends forming an actuation area of said at least one lever element.

9. The Dewar device according to claim 4 , wherein said at least one lever element comprises an actuation area capable of activating the push button of the watch by contacting at least one activation area of a middle.

10. The Dewar device according to claim 4 , wherein said at least one lever element comprises an actuation area capable of activating the push button of the watch by contacting at least one activation area of a middle, the activation area comprising a sliding member arranged in the middle capable of contacting the push button of the watch when the push button is acted upon by said at least one lever element.

11. The Dewar device according to claim 4 , wherein said at least one lever element comprises an actuation area capable of activating the push button of the watch by directly contacting said button.

12. The Dewar device according to claim 1 , wherein said enclosure is under vacuum or almost under vacuum.
