    • 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.
    • 本发明涉及一种钟表(1),包括以第一频率振荡并由第一齿轮系(5)连接到能量源(9)以显示时间的第一振荡器(15),以及计时系统(51),包括 经由耦合装置(44)连接到第一齿轮系(5)的第二齿轮系(25),用于选择性地测量时间。 根据本发明,计时器系统(51)还包括连接到第二齿轮系(25)并以第二频率振荡的第二振荡器(35)。 此外,第二齿轮系(25)通过弹性联接装置(41)连接到第一齿轮系(5),以便使用相同能量源(9)同步两个振荡器(15,35)的速率 )耦合装置授权所述时间测量。 本发明涉及包括计时码表系统的机械钟表领域。
