Abstract: The watch according to the present invention includes time-indicating means, time-setting means operable to set the time-indicating means, a setting shaft which is axially movable to first and second positions and arranged to be operatively connected to the time-setting means in the first position. Also included in the watch are rotatable calendar-indicating means provided with a circular series of teeth, a calendar-correcting pinion non-rotatably mounted on the setting shaft, a calendar-correcting shaft, which extends chordally at an angle to the setting shaft and has first and second end portions, first and second pinions non-rotatably mounted on the calendar-correcting shaft on the first and second end portions thereof, respectively.

Abstract: A stepping gear is rotatably mounted with freedom of axial movement and formed with an axially facing shoulder and with teeth and tooth spaces defined by said teeth. A rotatably mounted pawl roller has first and second peripheral rings. A spring urges said pawl roller against said stepping gear. The first peripheral ring is adapted to enter one of said tooth spaces to oppose a rotation of said stepping gear. The second peripheral ring radially overlaps said shoulder to limit the freedom of axial movement of said stepping gear.

Abstract: In a watch having a rotatably mounted date ring, a date-stepping mechanism for advancing the date ring comprises a stationary peripheral first series of teeth, a rotary drive element, a date-stepping finger, which is mounted to be rotatable and radially displaceable relative to said rotary drive element into and out of engagement with said first series of teeth and comprises a stepping pin, a forked end portion having first and second prongs, and a drive pin carried by said first prong.
