TIME RELAY FUNCTION

When the watch is in power save mode, the hands stop moving but the built-in IC continues to calculate the time. When a certain amount of electrical power is generated, the watch hands are adjusted automatically to the time retained inside the watch.

The operable time of the time relay function varies depending on the electrical energy stored inside the watch. In a case that the fully charged watch enters the power save mode, the time relay function of the watch remains operable for approximately four years.

If the stored electrical energy is completely depleted while the watch is in power save mode, swinging the watch will not activate the time relay function. Instead, the second hand starts moving at two-second intervals. (Refer to “HOW TO WAKE UP THE WATCH FROM POWER SAVE MODE” on page 10 or “IF THE SECOND HAND STARTS MOVING AT TWO-SECOND INTERVALS” on page 17. )
