Abstract

A watch including a case containing a plate and an electronic module powered by a button cell battery, a conductor electrically connecting the button cell battery to the electronic module and a clamping device capable of ensuring an electrical connection between the button cell battery and the conductor, wherein the clamping device includes a magnet.

Claims

1. A watch comprising a case containing a plate and an electronic module powered by a battery, a conductor electrically connecting the battery to the electronic module and a clamping device capable of ensuring an electrical connection between the battery and the conductor, wherein the clamping device includes a magnet, said magnet ensuring electrical conduction between the magnet and the conductor.

2. The method according to claim 1, wherein the conductor is flexible.

3. The method according to claim 2, wherein the conductor is a flat cable.

4. The watch according to claim 1, wherein the conductor is fixed to the magnet.

5. The watch according to claim 1, wherein the conductor is placed between the magnet and the battery.

6. The watch according to claim 4, wherein the magnet is placed between the conductor and the battery.

7. The watch according to claim 1, wherein the magnet includes a conductive surface.

8. The watch according to claim 7, wherein the magnet is made of a conductive material.

9. The watch according to claim 6, wherein the magnet is gold plated.

10. The watch according to claim 1, wherein the conductor is electrically insulated.
