Great quality
This is a great everyday sports watch. It feels durable, comfortable to wear, and looks good without being too bulky. It keeps time accurately and handles daily activities really well. I like it a lot and would recommend it.

Nice discrete G-Shock stealth that hides its size, and is care free comfortable.
This thing looks and feels smaller than it is, the angled roundness and blacked out scheme make it discrete on the wrist, hiding its thickness which is nice. It has all the standard features from stop watch to timer, easy to see even though its not one of the new MIP displays. It has acceptable for me viewability in low light, its not going to be perfect but that's the price for discrete inverted display. It helps that the cuff band is nice as it curves around the wrist instead of bending against due to cheaper watches floppy hinges. It makes it more comfortable and sit more appropriately on the wrist. The time is at the bottom and so closer to the front of your wrist, easier to see quickly. Its soft extra wide and more premium feeling than the cheaper watches. The backlight is very bright and clear. The few gripes are this, it doesn't show the clock time in timer mode in the corner like with the squares, it just has animation there instead, and the timer doesn't have an auto loop cycle. I've included a low light picture for reference. Very good day to day watch.

Nice Quality
I was very distraught at the condition the box came as per the video. The box was opened and contents were almost falling out. After inspection of the watch and the paperwork that came inside everything seems to be ok. There was no signs the watch had been previously been used. There was no scratches or dirt on the watch or wrist band. I have a 8.5” size wrist and the watch fits just right. Watch feels comfortable . Not too thick/thin for my wrist size. Im loving the blacked out negative display. I will have to see how it displays in the day time as im writing this review at night 😁. Rubber/plastic material doesn’t have a weird smell. Buttons are just big enough for my fingers to operate. I got this on sale so it makes it worth the money. Battery lufe will be TBD. If it’s the original from the manufacturer im not expecting a long life. Manual says 7yrs.

Great watch. 1 year review
I have had this watch over a year now and it is still functioning and looks like day one. I have been to multiple field training exercises with it and it has yet to show any signs of quiting. Within the first month that I owned it, I scratched the plastic front face pretty deep but thankfully that deep scratch disappeared within a week (didn't expect that, just thought I should share) it's almost like the plastic face to the watch is self repairing. The watch was a bit bulky the first week but you get used it quickly. The nice thing about that is it is likely to keep your sleeve up enough so that you can easily see the time. It has different functions that work well, the four button arrangement for functions can be a bit tricky at times but it becomes muscle memory soon enough. Over the past year I have only noticed it coming off my wrist twice which I'm sure can be expected with many watches just based on things pressing against the buckle certain ways/directions. If I lost this watch I would certainly buy again. The only thing I would look for differently would be to have an easier way to set alarms. At night in the field you can't use the watch light while attempting to set alarm because the light goes off every three seconds. Easily the best $60 I have spent for myself in a long time

A fashion statement, yet an enigma
Some have asked if this watch tells good time. First, no, it does not tell the time. You have to look at it and read the time yourself. Second, why should a watch tell good time? Whether or not you're having a goud time is based on choices and circumstances far outside Casio's control. Your time may be improved by this watch, however, because it's pretty neat. But this of course means quality of time. It still 60 seconds per minute. Casio can't improve that, unless their dark matter experiments pay off.
