Abstract

A modular watch ( 1 ) including at least a middle ( 10 ), a back ( 11 ), a display module ( 12 ) having a dial, time display, a crystal and a first magnetic gear, a horological module ( 13 ) including a horological movement with a second magnetic gear arranged to cooperate with the magnetic gear of the display module ( 12 ), and first and second bracelet strands integral with the middle ( 10 ) at a pair of horns ( 20, 30 ). The display module ( 12 ) and the horological module ( 13 ) are mounted one on top of the other, the display module ( 12 ) being mounted such that it is fixed against the middle (10), and the horological module ( 13 ) being mounted such that it can rotate between the back ( 11 ) and the display module ( 12 ) in order to set the time.

First claim

The invention claimed is:

1 . A modular watch comprising:
a middle; a back; a display module comprising a dial, time display means, a crystal and first magnetic gear means; and a horological module comprising a horological movement with second magnetic gear means arranged to cooperate with the magnetic gear means of the display module; wherein the display module and the horological module are mounted one on top of the other, said display module being mounted such that it is fixed against the middle, and the horological module being mounted such that it can rotate between the back and the display module in order to set the time.

2 . The modular watch according to claim 1 , wherein the magnetic gear means comprises a first minute wheel having at least one magnet, said first minute wheel being arranged to cooperate with a second minute wheel of the second magnetic gear means, said second minute wheel also having at least one magnet.

3 . The modular watch according to claim 1 , wherein the display module and horological module are both water-resistant.

4 . The modular watch according to claim 2 , wherein the display module and horological module are both water-resistant.

5 . The modular watch according to claim 1 , wherein the time display means comprise an hour hand and a minute hand.

6 . The modular watch according to claim 1 , further comprising means for locking the rotation of the horological module.

7 . The modular watch according to claim 6 , wherein the rotation locking means comprise a groove formed on the outer periphery of the horological module.

8 . The modular watch according to claim 7 , wherein the groove formed on the outer periphery of the horological module comprises Nx 60 notches, N being strictly greater than zero.

9 . The modular watch according to claim 1 , wherein the horological module comprises a mechanical movement or a quartz movement.

10 . The modular watch according to claim 1 , wherein the centre of rotation of the horological module, the centre of rotation of the first minute wheel and the centre of rotation of the second minute wheel are coaxial.
