The aforementioned 31-toothed wheel (7) is solidly connected to a corrector element (11). The drive means (2, 4, 9) comprise a cam (3) which is solidly connected to a wheel (2), a driving yoke (4), elastic means (6) which are used to press said yoke against the cam (3), a corrector yoke (9), a feeler (9b) which is arranged to detect the position of the year cam (22) and elastic means (9a) in order to connect said yokes (4, 9) to one another. |
