  • Patent number: 8842502
    Abstract: This watch movement part comprises a frame (1) bearing a striking work mechanism which comprises: a motor member (10) kinematically linked with a striking work wheel (20), a striking work hammer (40), an anchor (30) with two pallets (31, 32) engaged alternately with said striking work wheel (20) and cooperating with said striking work hammer (40) to make it oscillate between a first position striking a resonant member (50) and a second position, and a limiting spring (60) defining said second position, and wherein the anchor (30) and the striking work hammer (40) form a single striking work member mounted to pivot on the frame (1).
    Type: Grant

  • Patent number: 7457201
    Abstract: A golf counter is constructed in a completely mechanical manner and includes a first counting mechanism with a display (202) for counting a number of strokes per hole, a second counting mechanism with a display (203) of a total number of strokes, and a third counting mechanism with a display (204) of played holes, wherein a press button (212) for indexing the third counting mechanism to the next position automatically sets the first counting mechanism into a zero position. Thereby, the display of the second counting mechanism is a sum hand (203) which may be rotated about a central pivot of the golf counter. The sum hand (203) permits an analog representation of the state of the game, in contrast to the common two-or three digit displays with digit disks. The counting mechanism is preferably designed as an autonomous module, and is arranged in a watch between the dial and the clockwork.
