FIELD: watches and other time measuring instruments.
SUBSTANCE: present invention relates to timepieces (1) containing a first oscillator (15) oscillating at the first frequency (f1) and connected to the energy source (9) by a gear train (5), and another second oscillator (35) that oscillating at the second frequency (f2) and is connected to the second gear train (25). Second gear train (25) is connected to the first gear train (5) by an elastic coupling unit (41) to synchronize the rate of the two oscillators (15, 35), using the same energy source (9).
EFFECT: to synchronize the rate of two oscillators.
