Embodiment Construction

[0013] figure 1 and figure 2 Timepiece 1 in includes a chronograph whose hands 2 and 3 are driven by a first gear train 4 which in turn drives a resonator 5 . In particular, as figure 1 As shown, the chronograph given here as an example is fitted with a direct drive seconds hand 2 and a hand 3 mounted to an inverted minute counter. pointers 2 and 3 by figure 2 The first gear train 4 shown drives, wherein the direct drive seconds hand 2 (not shown) is mounted on a fourth wheel 21 forming part of the first gear train 4 . The minute counter driving the reverse hand 3 is not shown in the figures, but it is connected to the first gear train 4 in a known manner. The first gear train 4 in turn drives the first resonator 5 at the end of its stroke. This resonator has a balance with hairspring 22, on the arbour of which is fixed a roller 23 fitted with an impulse pin driven by a cooperating escape wheel 25. The pawl 24 is actuated and the escape wheel 25 is driven by the last w...

Abstract

The present invention relates to a timepiece including a chronograph and a watch. Hands of the chronograph are driven by a first gear train (4), which in turn drives a first resonator (5) and a watch whose hands are driven by a second gear train (8) independent of the first gear train, wherein the second gear train in turn drives a second resonator (9). The first (4) and second (8) gear trains are driven from a single energy source (10).

Description

technical field [0001] The invention relates to a timepiece comprising a chronograph and a watch. The pointer of the chronograph is driven by a first gear train which in turn drives a first resonator. The pointer of the watch is driven by a second gear train. The second gear train is independent of the first gear train, which in turn drives the second resonator. Background technique [0002] As is often the case in combined chronograph and watch timepieces, the gear train driving the chronograph is derived from the gear train driving the watch, and the timepiece typically has only a single energy source and a single resonator. As a specific example: in the document "Le Chronographe" (by Scriptar AS, LAconversion, (Switzerland), 1990) by B. Humbert, it is mentioned that the top pivot of the fourth wheel set of the watch is extended so that on it Install the wheel with face teeth or the first chronograph drive wheel. The first chronograph drive wheel is in permanent mesh wit...
