| 摘要 |
The invention relates to a timepiece (1) comprising a first oscillator (15) oscillating at a first frequency and connected by a first gear train (5) to an energy source (9) to display the time and a chronograph system (51) comprising a second gear train (25) connected to the first gear train (5) via a coupling device (44) for selectively measuring a time. According to the invention, the chronograph system (51) further comprises a second oscillator (35), which is connected to the second gear train (25) and oscillates at a second frequency. Moreover, the second gear train (25) is connected to the first gear train (5) by an elastic coupling means (41), in order to synchronise the rate of the two oscillators (15, 35) using the same energy source (9) when the coupling device authorises said time measurement. The invention concerns the field of mechanical timepieces comprising a chronograph system.
