Nice Watch
I giving 5 stars because I really like the looks and functionality of the watch. The hour/minute hands glow enough for me to tell the time in the dark. The only thing that needs help is a better light for setting alarms in the dark. If you are an Outdoors person (like me), I suggest using a Mini flashlight and strong teeth when trying to set alarms at night :-) Oh, I also am pleased with this watch band. This one is much softer than most of the rubber/synthetic bands that come with these watches. The first thing I usually do with a new watch is to find a much more comfortable band to fit. Not too easy with Casio G-Shock watches.

Watch arrived on time and in good condition. Other reviews were correct about it being a little hard to set up but reviewing a u tube video and it made it a lot easier. Nice looking timepiece. The LCD is a little hard to see but how many times a day are you gonna look at the date? Overall I'd give the watch 4.5 out 5.

Fits , feels, and looks great
You can most definitely read the second and minute hand. I know everyone complains about nighttime reading of the watch face. But unless you’re checking your watch, every five minutes, it’s not very complicated with the little light. If you just glanced down, check the time and that’s that. This is a really good looking, watch, and Fitz well, I absolutely love it! By the way, I don’t have the biggest wrist, and it fits me perfectly, and doesn’t look like I have a grandfather clock strapped on my arm.

Visibility poor
The watch looks nice and it’s a good alternative in being a smaller size than other g-shocks which are pretty large. However as the other reviews state, the digital display is difficult to see. Unless under ideal lighting it’s very difficult to make out. That aside it’s a nice looking watch.

Love The Options
Pros: Fits my 7-1/4" (7.25" / 184mm circumference) wrist quite comfortably with plenty of adjustment. I like the octagonal bezel with many different options of color and and dial. I enjoy the various modes it offers. It's nice being able to see UTC time and have timers as well as alarms. Since it's quartz/battery driven, I like not having to wind it or often adjusting the time compared to mechanical watches. Cons: I wish the hour and minute hand had a brighter luminescence but the on board light helps in the dark. It's also difficult to read the screen from 17min to 25min. Even worse from 3:17 to 3:25 when both the hour and minute hand are blocking the LCD screen. Overall: I love the watch. It has its minor issues but it wouldn't deter me.

FACE VERY HARD TO READ !
The watch is of course very accurate...that's a plus...but the black dial and blue markers are VERY hard to read, especially in low light. Even in bright light, including sunlight, you will need to have the watch at just the right angle to be able to read the digital "window". And even then, it's hard to see. I kept the watch, but really should have returned it. I purchased another version with a lighter dial that was easier to read. So this one stays in the drawer getting little or no time on my wrist. Bottomline...it looks good in the photos, but trust me, it's hard to read the dial!
