Good cheap watch. Watch band could be better
Color: Luminous watch black face
The timepiece itself is use of decent quality and is perfectly acceptable for everyday use. I'm pretty rough on my watches and this watch fits the bill as I go about my daily routine. It keeps good time and has a good looking face. It seems many have trouble with the watch band sizing. The arrows on the inside of the watch band show the direction the pins should be pushed out. The pins stick out ever so slightly on one side or the other of the watch band giving the band a rough feel. I used a soft nail file and polished the pins smooth. The watch band feels much better afterwards. I would buy it again and recommend the watch to anyone looking for a cheap timepiece.

unless you are adept at figuring out how to fix things , don't buy.
Color: Luminous watch black face
This watch looks good but it's not easy to remove the links , to make it shorter. Also the clasp broke right away! It was a waste of money for me.
