<P>PROBLEM TO BE SOLVED: To provide a clock where oscillation is maintained and power reserve is improved as well. <P>SOLUTION: A clock (1) oscillates in a first frequency (f<SB POS="POST">1</SB>) and is provided with a first resonator (R<SB POS="POST">1</SB>) connected by a main gear train (T<SB POS="POST">2</SB>) to a main energy source (B<SB POS="POST">2</SB>) via a main escapement (D<SB POS="POST">2</SB>). The clock (1) is provided with a second oscillator (R<SB POS="POST">2</SB>) which oscillates in a second frequency (f<SB POS="POST">2</SB>) lower than the first frequency (f<SB POS="POST">1</SB>), cooperates with the main escapement (D<SB POS="POST">2</SB>), and thus synchronizes maintenance of the first resonator (R<SB POS="POST">1</SB>) with the second frequency (f<SB POS="POST">2</SB>). The present invention is related to a field of connected oscillators. <P>COPYRIGHT: (C)2013,JPO&INPIT |
