Embodiment Construction

[0068] figure 1 An example of a retraction mechanism 1 according to the invention is shown. It includes a reverse indicator 2 shown in this embodiment in the form of a minute hand. The retracted minute indicator 2 is mounted on the shaft of the retracted movable member 20 . The retracting movable member 20 includes an external tooth portion 200 .

[0069] The rack 3 has a first end 31 pressed against the periphery of the snail cam 5 by means of a rack spring 33 . The second end 32 of the rack 3 comprises an oblong opening equipped with internal toothing 320 . The rack 3 pivots from the pivot point under the action of the snail cam. During this pivoting, the inner toothing 320 of the second end 32 of the rack engages the outer toothing 200 of the retractable movable part 20 so that the retractable indicator 2 carried by the retractively movable part 20 moves along with the The second end 32 of the rack turns in the same direction. The movement of the toothed rack is trans...

Abstract

A mechanism (1) for watch movement, the mechanism comprising: a cam (5); a rack (3) driven by the cam (5); a retractable movable member (20), which is driven by the rack (3) ) drives and carries the retraction indicator (2) for displaying the first item of time information, the rack (3) and the retraction movable member (20) are arranged to rotate in the same direction. The jump hour display ring is synchronized with the return of the rewind display.

Description

technical field [0001] The invention relates to a mechanism for a watch movement with reverse and jump displays. Background technique [0002] Retrograde displays are known in the watch industry, which are displays in which the hands or dial are rotated in one direction for a given period of time and then almost instantaneously at the end of the period by rotating rapidly in the opposite direction. Jump back to the original position. These reversed displays are used, for example, to indicate the minutes on a scale from 1 to 60 covering a circular arc below 360°. These fallback displays make it possible to free up space on the dial for indicating other information. In addition, the rapid return of the minute indicator every hour creates movement on the dial. [0003] Jumping displays are also known, in which the time indicator jumps almost instantaneously from one value to another. These jumping displays are used in particular to display the date in the window. They are ...
