A timepiece includes a case in which an electronic module supplying at least one item of information is arranged. The at least one item of information is displayed on a dial by a display. The electronic module also includes a communication unit having an optical receiving device. The optical receiving device includes at least one photoelectric receiver arranged to face a first aperture formed on the dial so that an optical signal can be received by the optical receiver.

Universal moon phase display device for a watch, comprising first means for calculating or receiving the date and second means for receiving a geolocation signal, and third means for calculating or receiving a lunar calendar with the correlation between the date of the moon phase, position calculating means arranged to convert the day's moon phase into a first angular position of a first display member comprised in this device and which comprises a representation of the normal moon, and further arranged to determine the northern or southern hemisphere in which this device is located, to control the direction of rotation of first drive means comprised in this device in order to drive the first display member in opposite directions in the northern hemisphere and in the southern hemisphere.

The timepiece movement is provided with an analog display device for an item of information whose value varies periodically or intermittently, this analog display device including an indicator for said information provided with a toothing and a mechanism for the periodic or intermittent driving of the indicator, this mechanism comprising a rotating wheel set whose pinion, in a meshing relationship with the toothing, is formed of two pins which are diametrically opposite relative to the rotational axis of the rotating wheel set, these two pins being configured to alternately penetrate successive hollows in the toothing and to form a self-locking system when the timepiece movement is subjected to shocks. Each of the two pins has, in a general plane of the toothing perpendicular to the axis of rotation of the rotating wheel set, a transverse profile having a first outer portion substantially in the arc of a circle centered on the axis of rotation.

The present invention relates to a timepiece comprising a case, in which an electronic module supplying at least one item of information is arranged, wherein said at least one item of information is displayed on a dial by display means, characterised in that the electronic module additionally comprises a communication unit having an optical receiving device, wherein said optical receiving device comprises at least one photoelectric receiver arranged to face a first aperture formed on the dial so that an optical signal can be received by said optical receiver.

A device which is suitable for integration into a timepiece, in particular in the form of a timepiece module, another type of watch module or a basic watch movement. The device includes at least one opening, in each of which an associated image guide is mounted, and for each of these image guides the device including means for fastening the image guide in the associated opening, such that the image guide allows display information displayed on a representation plane to be reproduced on a display plane.

A timekeeping device including a first dial including a plurality of first dial display regions, each of the plurality of first dial display regions disposed at an angle of 90-degrees with respect to each adjacent first dial display region and a center of the first dial, a second dial disposed adjacent the first dial and configured to rotate in two directions about a central axis of rotation of the second dial, and a set of two adjacent third dials disposed adjacent the second dial, each dial of the set of two adjacent third dials configured to rotate about a respective central axis of rotation, the set of two adjacent third dials each comprising indicia representing at least one value configured to represent a date of a month.

Disclosed is an electronic device, including: a base including: a first mounting part that includes a main surface provided in an annular shape; a second mounting part that is provided at an inner side of the first mounting part and includes a main surface and a raised part raised upward; and a third mounting part that is provided around the first mounting part; and an annular calendar disk that has a thickness smaller than a difference between a height of the raised part of the second mounting part and a height of the main surface of the third mounting part and includes an inner peripheral side partly disposed on the second mounting part. The main surface of the second mounting part and the raised part are both lower than a main surface of the third mounting part and higher than the main surface of the first mounting part.

An electronic timepiece includes a rotatable annular member, a substrate having at least one protrusion, and a sheet-like component disposed between the substrate and the annular member. The sheet-like component is controlled in position by the at least one protrusion. The annular member is supported by the at least one protrusion.
