| 发明名称 | Timepiece with coupled oscillators in chronograph mode | ||
| 摘要 | A timepiece includes a first oscillator oscillating at a first frequency and connected by a first gear train to an energy source to display the time. The timepiece also includes a chronograph system including a second gear train connected to the first gear train via a coupling device for selectively measuring a time. The chronograph system further includes a second oscillator, which is connected to the second gear train and oscillates at a second frequency. Moreover, the second gear train is connected to the first gear train by an elastic coupling, in order to synchronize the rate of the two oscillators using the same energy source when the coupling device is in a coupled position. | ||

| 主权项 | 1. A timepiece, comprising: a first oscillator comprising a first resonator and a first escapement, and the first oscillator oscillates at a first frequency and is connected by a first gear train to an energy source for displaying the time; and a chronograph system comprising a second gear train connected to the first gear train via a coupling device for selectively measuring a time, wherein the chronograph system further includes a second oscillator comprising a second resonator and a second escapement, and the second oscillator is connected to the second gear train and oscillates at a second frequency, and wherein the second gear train is connected to the first gear train by an elastic coupling means in order to synchronise the rate of the two oscillators using the same energy source when the coupling device is in a coupled position. | ||
