Casio G-Shock Rescue Series Solar Atomic GW-7900B-1CR Mens Watch
It’s all black with an inverted digital face. For low-light situations, the G-button lights up the screen. And you can do that too without pushing the button. All you have to do is flick your wrist. Almost an inch thick, it’s a large one but disturbingly light. That’s due to the scratch-resistant plastics it’s made from.
An automatic time-setting (and checking) through atomic clock radio signals is its prime highlight. And run on solar power, there’s no need changing batteries and spoiling the factory seals. On a full charge, it will last for about 9 months. A super accurate piece.
