More Information
Summary:The watch mechanism includes a casing (8) having a base (10) and a frame (12) made in a single piece. A control shaft (26) cooperates with a retaining tab (44) and extractor device (48) to allow a part of the retaining tab to engage the control shaft (26). The extractor includes a first branch (50) which slides in the movement (2) in a direction perpendicular to the plane of the movement with the end facing the retaining tab, and a second branch (52) which comprises a portion facing the outside of the movement (2) to form a gripping arm. The extractor element (48) is movable between a first rest position in which it does not act on the retaining tab (44), and a second operational position in which the end of the first branch (50) presses the tab into the channel holding the control shaft (26).
