Embodiment Construction

[0051] exist figure 1 , the wrist watch according to the invention is presented without a watch case, without a watch dial and without other constituent parts known per se and not directly related to the invention. Reference numeral 1 designates a clock movement to which a perpetual calendar mechanism 2 according to the invention is attached. A gear train 3 couples the hour mobile 4 of the timepiece movement 1 to a toothed wheel 5 integral with a finger 6 .

[0052] Like the gear 5, the fingers 6 make one revolution per day. It is designed to manipulate the actuating lever 9 once a day by acting on a catch 10 of the actuating lever 9 .

[0053] A spring 12 is arranged to return the actuating lever 9 to the waiting position after each actuation of the actuating lever 9 . In addition to the spring 12 , the actuating lever 9 also comprises a toothed rack 13 which engages with a complementary toothed rack 20 equipped with the lever 21 .

[0054] The lever 21 supports a pivotab...

Abstract

In the annual or perpetual calendar mechanism, the month-day moving part (23) includes a notch (63) and a month-day wheel (23). Each time the lever (21) is actuated, the first detent finger (50) achieves a one-step actuation on one of the teeth (61, 62, 64) of the day-of-the-month (23). When the lever (21) is actuated at the end of a month of less than thirty-one days, the second pawl finger (51) realizes an integer number of steps of the day-of-month movement (23) on the lever (63) actuate. The lever (63) is positioned between two consecutive teeth (61, 64) among the teeth (61, 62, 64) of the day-of-the-month (23). The day-of-the-month (23) has a peripheral edge that outlines the teeth of the day-of-the-month and the notch (63).

Description

technical field [0001] The invention relates to the field of watchmaking. More specifically, the invention relates to an annual or perpetual calendar mechanism and a timepiece comprising said mechanism. Background technique [0002] A watch may be equipped with a display presenting one or more pieces of information relating to the current date, including the day of the month. This display is controlled by a mechanism, such as an annual or perpetual calendar mechanism, driven by the movement of the watch. [0003] The annual calendar mechanism takes into account the existence of months in the Gregorian calendar with fewer than thirty-one days, and performs corrections at the end of each of these months, causing the excess one or more days of the month to elapse rapidly until the end of the following month. first day. The perpetual calendar mechanism performs the same correction as the annual calendar mechanism, and in February of a leap year, it performs a correction that ...
