Abstract: The calendar mechanism for a watch includes two rotating indicators provided with respective toothed wheels (11, 14), indicating for example the date and the phase of the moon or the day of the week, and drive lever (21) provided with two beaks (22, 23) for making the corresponding indicator move forward one step, depending upon whether it is pivoting in one direction or the other. The daily movement forward of the indicators is assured by a drive wheel (20) making one revolution per day and provided with a pin (38) which cooperates with a cam surface (33) of the drive lever. In order to correct the indicators independently of each other, a gear train (44) actuated by a control stem of the watch causes a correction wheel (50) to rotate, which acts on a nose of the drive lever (21) to pivot the latter selectively in one direction or the other.

Abstract: The watch disclosed has a case of ovoidal shape, wherein a circular watch movement (5) is arranged off-center, on the side of the end of the case with the larger radius. On the side of the other end there is a moon phase indicator disc (16) and a power-reserve indicator of the watch. The moon disc is driven step-by-step by the movement (5) via a control lever (35) having a beak (43) that drives an external toothing (44) of the disc. This lever extends at least partly along one edge of the case, where a correction push-button is mounted, that can activate (P) the lever in the same direction as the movement is driving, which prevents any interference between the two actions.
