## Description

Casio G-Shock MB-6 GW7900B-1 Atomic Solar Rescue Multi-Band 6 Wristwatch

Review: Watch - Very good
Review: Good, but not great... - This watch looks great - it's 'stealth' black look is mean, and a real fashion statement. As is the size. A 50mm width, and 15mm height ensures it will be noticed. However, the display is a double edged sword. The negative display keeps within the stealth mode, BUT it is impossible to read in low light conditions without the aid of the EL light. By low light, I mean indoors under domestic conditions (not bright office light), or outdoor in winter. Sunshine really pops the display into life. The functionality is superb, the atomic function ensures 'to the second' accuracy, and being solar means the watch will remain intact without costly battery replacements, and new gaskets to retain it's waterproof qualities. The resin strap is of good quality, and is supremely comfortable due in part to the 'wings' at either side of the lugs which hug your wrist. I have had mine for some months now, and have 'modded' it slightly by replacing the chrome buckle with a black one, removing the white writing around the bezel, and replacing the silver bezel rivets with black ones, and painting the 'G' on the light button black, all just to highlight the stealthiness of the design. I do love it, and it is almost a great watch, apart from the fact that you can't tell the time in poor light!!

### ⭐⭐⭐⭐ Display is hard to read
*by E***E on 15 October 2022*

I’ve had this for the past few years and it’s great watch in every way except two things are a pain. The negative display looks cool but it’s really hard to read most of the time and you spend more time moving your wrist to catch the right angle to read it, or have to illuminate it. The solar power indicator and hourly time signal are tooooo small to see half the time. Would I recommend buying one? No, get the normal version.
