An electronic timepiece device including an electronic processing unit determining first, geolocation parameters and second parameters concerning the current legal standard time, and establishing local horizontal coordinates of the Sun from predetermined calculation rules stored in a memory of the electronic processing unit. The device also has a dial equipped with a casing enclosing all or part of the electronic processing unit and equipped with a display system displaying at least one indicator hand having an orientation that varies over time such that the angle formed between the indicator hand and a first fixed reference axis of the dial is equal, at each instant, to the azimuth of the Sun established by the processing unit, and a time scale calculated by the electronic processing unit and displayed at the periphery of the dial in the form of a plurality of time points positioned, with respect to the first fixed reference axis, as a function of the azimuth of the Sun respectively at the times of which the time points are representative. Thus the indicator needle simultaneously indicates, at each instant, a representation of the relative directions of the Sun and of the cardinal point of the culmination of the Sun and the current legal time.

The present invention relates to a device (100) for displaying the moon for a timepiece on demand. The display device (100) comprises a first movable indicator member (110) and having a representation of the moon (111). This representation of the moon (111) is completely or partially occulted by an occulting element (121) that is located on a second movable indicator member (120) when the user so requests and in particular via a control unit.

A moon phase display includes a frame and a plurality of display elements supported by the frame and rotatable relative to the frame. The plurality of display elements further includes a first side face on which an illuminated moon portion is depicted and a second side face. A first rotational position in which the first side face is arranged along a display plane wherein the first side faces together arranged on along the display plane represent a full moon. A second rotational position in which the second side face is arranged along the display plane. A drive rotates each of the plurality of display elements independently. A controller actuates the drive so that each one of the plurality of display elements is rotated into the second rotational position until all of the plurality of display elements are located in the second rotational position.
