●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. )

SCREW LOCK TYPE CROWN

●Some models have the screw lock type crown, which can be locked by the screw

when it is not necessary to be operated.

●Locking the crown will prevent operating errors.

●Unscrew the crown before any crown operation. When the operation is over,

screw the crown in to lock.

If your watch has a screw lock type crown, unscrew it before any crown operation.

❖

Always keep the crown locked unless it is necessary for operating the crown.

Turn the crown counterclockwise (down-

ward) to unscrew it. The crown is unlocked

and can be operated.

The crown can be pulled out.

Upon completion of the crown operation,

screw the crown in completely until it stops

by turning it clockwise (upward) while gen-

tly pressing it back into the original position.

Turn the crown while pressing

it back in.
