Nice watch. The only bad thing is the clasps on the wrist band is horrible. One little bump and it opens up and then you have to try to catch the watch in case it completely falls off. I'd recommend only buying this if you are willing to change the wristband out otherwise half the time you will be fighting it from opening up and slipping off.

Best watch for 40 bucks

Works well, tells time, bang for your buck. People are complaining about esthetics and breaking after a while. You're spending 40 bucks on a watch what do you expect? Cmon. Its good for the price buy this one if you want something cheap, functional, and stylish.

Buitfiful watch

Color: Blue Face/Silver Strap

Buitfiful watch with a good weight. The size adjuster only really works though if you unscrew it completely and just push the pins out with that. But other than that it's a buitfiful watch.
