Abstract (en)
[origin: EP2570870A1] The timepiece (1) has an oscillator (15) oscillating at frequency and connected to an energy source (9) by a gear train (5), and another oscillator (35) oscillating at another frequency and connected to another gear train (25). The latter train is connected to the former train by an elastic coupling unit (41) in order to synchronize rate of the two oscillators using the same energy source. The elastic coupling unit is formed by a spring (43) connecting a wheel of the former train to another wheel of the latter train. The two frequencies are identical and higher than 5 hertz.
