Abstract:
The present invention relates to an adjustment device (10) for a watch arranged such as to be clamped onto the glass of a watch (100) and comprising a plurality of display means (106). The device is arranged such as to allow the user to view said display means (106) of said watch during the adjustment thereof.
Abstract:
The electronic clock movement comprises an analog display device with a date ring (6) and a stop watch hand (4) associated with a graduation (5) of a usual small counter. This ring and this hand are driven by one and the same electric motor (10) via a set of permanent gears, the stop watch hand being mounted on a wheel of this set of permanent gears which wheel is arranged between the driving pinion (14) and a runner comprising a date drive wheel (24). The date ring and the date drive wheel respectively comprise two tooth sets forming a permanent mesh with a relatively large amount of lash making it possible to define a determined angular dead zone for the date drive wheel because the date ring is positioned by a jumper. This angular dead zone is used to drive the stop watch hand independently of the date ring. The set of permanent gears is arranged in such a way that the torque for positioning the rotor gives rise, at the date drive wheel, to enough of a blocking torque to perform a shock-proof function.
