Excellent Time Keeper // Terrible Wristband !
The watch itself is fantastic. When I first got it, and set it up, I set it to the time on my computer, which is as accurate as you can get. In the beginning I checked the time accuracy daily. After a few weeks my time checks changed to once, or twice a week. I never had to change the watch's time. The seconds would vary a little, in comparison to the computer clock. But, it never got more than 30 seconds either side of the computer clock. However, the watchband is a big time NO-GO! The buckle, where you connect it on your wrist, can be frustrating most of the time when you are trying to put it on. Once you've got it on, the strap that goes beyond the buckle is held down by a sliding keeper, that slides in and out depending on what you're doing. Terrible design! I wanted to buy a "Twist-a-Flex" wristband, but couldn't find one that matched the unusual design where the straps attach to the watch body. I bought the watch 4 months ago. Today, one of the 4 pins, that connect the straps to the watch body, fell out somewhere, making the watch impossible to wear. Excellent price. Excellent timepiece. Worst design for a wristband that I've ever seen.

Excellent for price, you won't be sorry
If you are looking for a watch with a lot of features that doesn't cost a lot, this is your watch. I tear up watches fairly easily in my line of work and after I killed my Seiko I decided I would hunt out a cheap watch. There aren't a lot of watches at this price range that include a stopwatch, date (with day of the week), AND has a light that is bright enough to actually read the time in the dark. This one does.
The watch not dainty; it is big and bulky, bigger than I thought it would be, but not unwieldy and not super heavy. Expect it to be big. This also helps with readability (My son can read the time on this watch from the other side of the couch).
The band feels rugged, made of a pliable and soft- feeling rubber and has a two- pronged belt- like closure (think 'biker belt') that keeps it secure on the wrist. Additionally, the holes for the band goes the entire length of the band so it is adjustable for really small wrists up to about 9.25" circumference.
Others have complained about how easily the face scratches, but I suspect they've failed to remove the protective coating on the lens. It's a protective film that you have to get your fingernail under to pull off. Once that's off, the lens is crystal clear and fairly tough. I've had mine for a week now and used it under some fairly harsh conditions and the lens is still clear and scratch-free.
My only complaint seems petty for a watch at this price point, but the strap-end hold down 'belt'--- the loop that holds down the extra length of the strap when it's buckled--- moves easily and so in use it will occasionally come off and you have to retuck the end back into it. But seriously, this is really minor.
If you need an inexpensive digital that's easy to read in both daylight and darkness, ya don't mind a large and bulky, rugged- looking watch, and don't want to spend an arm and a leg, get this one. You likely won't be sorry.
