Overall the watch is ok. The price doesn't reflect the quality of the watch. This should be a $20.00 dollar watch. I purchased this partially because I thought the number would glow at night, they do not. The hour and minute hand barely glow at night. I decided to just keep it, rather than returning it, and now I wish I had just returned it. After 2 months, I got a scratch on the watch, what looks like cheap, plastic. I can't say I would recommend it for that reason, I'm a average field watch wearer, which means they have to be somewhat durable. This was disappointing.
