Manual power save function

The power save function can be activated manually. If you decide not to use the watch

for a long time, use this function to further conserve energy.

POWER SAVE FUNCTION

● If the watch is left untouched for approximately 3 days, the hands will stop moving to

minimize the electrical energy consumed.

● More specifically, the power save function is activated if the generating system of the watch

remains inactive and no charging is done for approximately 72 hours.

● Even if the watch is not worn for more than 3 days, the power save function will not be

activated if the watch senses enough activity to start the generating system working during

the 3 days.

● Though the hands stop, the built-in IC continues to compute the time.

* While the second hand is moving at two-second intervals, the power save function cannot be

activated manually. In this case, charge the watch referring to “ENERGY DEPLETION FOREWARNING

FUNCTION”, and then, follow the procedure below.
