Abstract

A timepiece including a timepiece movement and sunrise and sunset indicating device that take account of the date and geolocation of the user, the device including a first device for receiving the current date, a second device for receiving a geolocation signal, and a disc bearing a representation of the sun, arranged to be capable of pivoting about an axis passing through the centre of the disc. The sunrise and sunset indicating device include a movable horizon arranged to move above the disc and to indicate the position of the sun with respect to the horizon.

First claim

The invention claimed is:

1. A timepiece comprising:
a timepiece movement and sunrise and sunset indicating means that take account of the date and geolocation of the user, said means comprising first means for receiving the current date, second means for receiving a geolocation signal, and a disc bearing a representation of the sun, arranged to be capable of pivoting about an axis passing through the centre of the disc, wherein the sunrise and sunset indicating means comprise a movable horizon arranged to move above the disc and to indicate the position of the sun with respect to the horizon,
wherein said horizon includes a rack arranged to cooperate with a pinion kinematically connected to the timepiece movement, and
wherein the rack is guided in translation by a pair of pins extending downward from the horizon to slide in a groove made in the timepiece movement, the pair of pins move in translation with the rack and the horizon, and the pair of pins includes a first pin arranged on an opposite side of the movable from a second pin.

2. The timepiece comprising sunrise and sunset indicating means according to claim 1 , wherein said movable horizon and the rack are in one piece.

3. The timepiece comprising sunrise and sunset indicating means according to claim 1 , wherein the horizon is opaque.

4. The timepiece comprising sunrise and sunset indicating means according to claim 1 , wherein the horizon is semi-transparent.

5. The timepiece according to claim 1 , wherein said first means for receiving the current date are means for receiving a signal transmitted by a satellite or by a mobile telephony device arranged to be carried by the user of said watch.

6. The timepiece according to claim 1 , wherein said second means for receiving a geolocation signal and/or a signal indicating the terrestrial hemisphere of a place are means for receiving a signal transmitted by a satellite or by a mobile telephony device arranged to be carried by the user of said watch.

7. A portable assembly comprising a watch according to claim 1 and a mobile telephony device arranged to provide a geolocation signal or information and/or a signal or information indicating the terrestrial hemisphere of a place, and/or a date signal or information to said watch.

8. The timepiece according to claim 1 , wherein said rack extends outwardly from a perimeter of the horizon.

9. The timepiece according to claim 1 , wherein said horizon is positioned between the first pin and the second pin.
