Instructions for Setting a Casio G-5110 Shock Wristwatch

Casio's G-Shock watches are designed to survive hard impacts, dirt and water. But a G-Shock's rugged features are virtually useless if it is not set with the correct time. The G-5110 is actually two different clocks in a single watch. It has an internal digital clock, which it can display on the LCD screen on the right side of the watch face, and an external analogue clock, represented by the watch hands on the face. Each clock needs to be set independently for the watch to show the correct time.
