I've owned this watch now for about 2 years. I bought it online without trying it first. It's held up well to abuse. I have one scratch right in the middle of the display but it's only minor.

It fits really well on my wrist and I have typical wrists. I love the military styling. Wearing it makes me feel like I'm in special forces. The light green characters on top of a black screen add to the effect.

I used to run with it and noticed the display was hard to read while bouncing up and down. The lap times are shown in smaller font on the stopwatch screen. I don't really know how to fix that other than bigger display characters.

I have used it for ocean and lake scuba diving. My max depth with the watch is 110' so far. No issues with water proofing. I was happy with that since my previous watch was also water resistant but blew at a depth of only 14 feet.

I also used it for swim laps and it works well for that too. It was kind of fun to hear the chirp underwater.

Like the other reviews, the white on black looks cool but it is hard to read in low light without activating the light. This is where the watch fails my satisfaction. The illumination only lasts for one second and if you touch ANY button while illuminated, the illumination turns off. What?! Try setting an alarm in the dark or scrolling through the various screens. It's very frustrating. The light button is recessed which makes it difficult to depress. It's impossible to depress with gloves on, or especially neoprene scuba gloves. Forget about it. The wrist strap is not long enough to fit around a wet suit sleeve. I'm sure there are strap extenders to buy but I just end up strapping it to my BCD instead, which makes it inconvenient to read while diving and I track my bottom time very closely.

Other than that, I like the watch. It has many features I never have any use for. It tells you how many days are left in the year too. How many times have you wondered that in the middle of February?! Like right now, there are 311 days left. Woohoo!

I won't buy it again because of the illumination issue alone. I just don't understand why Casio would let that get out of the design department. I know next time I buy a watch I will try it on and test the light better.
