<p>An electronically controlled timepiece comprises a mechanical energy source (1a), a generator (20), driven by the mechanical energy source (1a), for outputting electrical energy, and a rotation controller (50), driven by electrical energy, for controlling the rotation period of the generator (20), the electronically controlled timepiece comprising:
a main storage unit (31) for storing electrical energy supplied by the generator (20) to drive the rotation controller (50),
an auxiliary storage unit (32) connected in parallel with the main storage unit (31) through a mechanically driven switch (361) that is interlocked with a time correction operation,
and a charge control circuit (35), arranged between the main storage unit (31) and the auxiliary storage unit (32), for adjusting charging currents to the main storage unit (31) and the auxiliary storage unit (32), and a direction and a magnitude of a current flowing between the main storage unit (31) and the auxiliary storage unit (32).</p> |
