Abstract: A device for the date indication in a watch, with a digit disk and a decimal disk, which each include a sequence of figures or numbers and are arranged next to each other in parallel in such a manner that they overlap within the region of an indicating position and thus allow to represent a two digit number visible through a corresponding date window in the dial. The disk of larger diameter is a circular disk and the axis of rotation of the disk of smaller diameter is arranged within the outer peripheral contour of the disk of larger diameter. The device includes a digit programme wheel and a decimal programme wheel, which control via a digit pinion and a decimal pinion the switching operation of the digit disk and the decimal disk, and a programme drive wheel, which passes on the driving force onto the digit and decimal programme wheels.

Abstract: The present invention refers to a constant-force device suitable for being integrated into a movement of watches, particularly wrist watches, with an indirect-second mechanism having an intermediate second pinion (14) driven by a second wheel (9) of the movement, and an indirect-second wheel (15). The constant-force device comprises a tensioning module (4, 5, 6, 7, 8), a cam (2), a lever (11), and a stop wheel (13). The stop wheel (13) of the constant-force device is mounted on the intermediate second pinion (14) of the indirect-second mechanism.

Abstract: The present invention refers to a device for the date indication in a watch, in particular a wrist watch, with a digit disk (9) and a decimal disk (6), which each comprise a sequence of figures or numbers and are arranged next to each other in parallel in such a manner that they overlap within the region of an indicating position (61) and thus allow to represent a two digit number, which is visible through a corresponding date window in the dial of the watch. The disk of larger diameter is designed as a circular disk and the axis of rotation of the disk of smaller diameter is arranged within the outer peripheral contour of the disk of larger diameter.
