  • Timepiece movement
    Patent number: 6687192
    Abstract: The invention concerns the structure of a timepiece movement, more particularly the structure of the hour wheel (1), the inside of whose pipe (4) includes an annular bulge (6) co-operating with an annular groove (22) arranged on the outer wall of the pipe (21) of the cannon-pinion (7). Thus, the hour wheel is snap-fitted onto the movement, without it being necessary to provide an additional part for this purpose, and its toothed wheel (3) cannot therefore be released from the motion-work pinion (19) during transport of the movement.

  • Method for manufacturing a display element for a timepiece and display element manufactured in accordance with such method
    Patent number: 6668456
    Abstract: In order to manufacture the display element intended for a timepiece, a sheet of plastic material shaped in a tape (3) is provided. The sheet is then deformed using tools (4, 6) by thermoforming to give it a profile (10, 11, 13, B) corresponding to the outer contour (20) of said elements.
