Abstract

A tool for actuating a corrector push-button fitted in a small portable object, wherein this actuation tool includes a body which extends between a rear end which defines a gripping zone of the actuation tool and a front end which defines an actuation zone of the actuation tool, at least the front end of the actuation tool being magnetised.

First claim

What is claimed is:

1. An assembly comprising:
a watch including a corrector push-button; and
an actuation tool for actuating the corrector push-button fitted in the watch,
wherein the actuation tool comprises a body which extends between a rear end which defines a gripping zone of the actuation tool and a front end which defines an actuation zone of the actuation tool,
wherein at least the front end of the actuation tool is made of a ferromagnetic material,
wherein the watch comprises a middle in an opening whereof is arranged a corrector push-button, the corrector push-button including a socket, a control rod that is movable within the socket, and a spring that is compressed when the control rod is pressed into the socket,
wherein at least one component of the corrector push-button or at least one portion of the middle immediately surrounding the corrector push-button is made of a magnetised material.

2. The assembly according to claim 1 , wherein the control rod is made of the magnetised material and the at least one portion of the middle is made of non-magnetisable material.

3. The assembly according to claim 1 , wherein the control rod is made of non-magnetisable material and the at least one portion of the middle is made of the magnetised material.

4. The assembly according to claim 3 , wherein the at least one portion of the middle is made of the magnetised material includes a ring arranged concentrically around the socket.

5. The assembly according to claim 3 , wherein the at least one portion of the middle is made of the magnetised material includes two studs arranged in a diametrically opposed manner relative to a center of the corrector push-button.

6. The assembly according to claim 3 , wherein the at least one portion of the middle is made of the magnetised material includes two discrete bipolar magnets arranged in a diametrically opposed manner relative to a center of the corrector push-button.

7. The assembly according to claim 3 , wherein the at least one portion of the middle is made of the magnetised material includes an annular magnet arranged around the socket.

8. The assembly according to claim 3 , wherein the actuation tool comprises a bar magnet arranged in the front end thereof.

9. The assembly according to claim 3 , wherein the body of the actuation tool is made of a magnetic material.
