Note on Screw-Lock Crown

Some water-resistant watch models are equipped with a screw-lock crown. To pull out such a crown, you must unlock it by turning it in the direction indicated in the illustration [arrow pointing right]. Do not use excessive force when pulling out the crown, as this may cause damage. Note that the watch is no longer protected against water and moisture when the crown is pulled out. After completing all operations using the crown, return it to its original position and lock it.

Watches with Backlight

Press and hold button L to illuminate the watch face. The backlight duration varies by model: from 2 to 3 seconds, 1 second, or while button L is pressed (Module 5577). The backlight is achieved using electroluminescent (EL) elements or LEDs. EL elements may lose power after prolonged use. Frequent use of the backlight shortens battery life. Turning on the backlight for an extended period or with a low battery may cause the hands to stop moving for a while.

Watches with Rotating Bezel

Rotate the bezel to align the mark with the minute hand. After some time, you can tell how much time has passed since you aligned the mark with the minute hand.
