Problems solved by technology

This solution is not optimal because it does not provide a complete indication of the week, because the surface area of ​​the day indicator is too small, which explains the fact that the week indication is abbreviated here
Also, the day of the week indications are repetitive, which can make the adjustment of the day of the week indications somewhat unergonomic

Embodiment Construction

[0017] referenced below Figure 1 to Figure 7 One embodiment of timer 300 is described. For example, a chronograph is a watch or wrist watch. The timepiece comprises a chronograph movement, such as an electronic or mechanical movement 200, in particular an automatic chronograph movement. The chronograph may also comprise a chronograph assembly, in particular a case for housing the movement.

[0018] The chronograph movement includes a calendar device 100 . The chronograph calendar mechanism consists of:

[0019] - a first disc 1 for displaying the date, having a first face 11 bearing a date indication 10 and movable about an axis A, and

[0020] - A second disc 2 for displaying the day of the week, which has a second face 21 bearing a day indication 20 and is movable about axis A.

[0021] The first and second plates are such that the first and second faces are coplanar. In other words, the day indicator or indication and the day of the week indicator or indication lie i...

Abstract

The invention relates to a timepiece calendar device (100) including a first display disk (1) for displaying dates having a first face (11) bearing date indications (10) and mobile about an axis (A),and a second display disk (2) for displaying days having a second face (21) bearing day indications (20) and mobile about the axis (A), the first and second disks being such that the first and secondfaces are coplanar, the second face being disposed around the first face.

Description

technical field [0001] The invention relates to a timer calendar device. The invention also relates to a chronograph movement comprising such a chronograph-calendar device. The invention finally relates to a timepiece, in particular a wristwatch, comprising such a chronograph-calendar device or such a movement. Background technique [0002] For example, the Rolex caliber 3255 is known, which includes calendar means adapted to display a day indication and a date indication. A day indicator is provided on the outer periphery of the date indicator so as to indicate a complete day of the week. This setup requires superimposing the day indicator and day indicator in two different planes. For this purpose, the disc bearing the indication of the day includes a window in which the indication of the day can appear. This scheme is very easy to read, but the axial offset of the day indication and date indication is very small. [0003] Also known is the ETA 2836 movement, which al...
