Embodiment Construction

[0026] The following will refer to Figures 1 to 3 One embodiment of the electronic timepiece mechanism 2 according to the present invention is described. The electronic timepiece mechanism comprises analog display means formed by first indication means 4 of first information and second indication means 6 of second information, said second information being of the type that changes periodically or intermittently. In the variant shown, the first information is a timed interval of time and the first indicating means is a stopwatch hand associated with a small dial at 6 o'clock arranged below the central axis of the timepiece mechanism. In particular, the pointer is a 30-minute counter pointer whose dial 5 is at figure 2 partially shown in. In the variant shown, the second information is a date indication through a window mounted on the face of the timepiece, and the second indicating means is a date ring (also called a date disc). It should be noted that the two pieces of in...

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.

Description

technical field [0001] The present invention relates to an electronic timepiece mechanism including an analog display device for multiple variable information. [0002] More specifically, the invention relates to an electronic timepiece mechanism comprising drive means for driving an analog display means of at least two pieces of information, actuated by the same electromechanical motor, of which at least A piece of information that changes periodically or intermittently between predetermined discrete values. The periodically or intermittently changing information is in particular date information and / or information related to a function / application selected from a plurality of possible functions / applications. [0003] In the context of the present invention, an indication device of periodically or intermittently changing information is associated with a periodic or intermittent drive mechanism characterized in that it is not in the electromechanical The indicating device is...
