I bought a return. It was 5 bucks cheaper. It looks nice and wears well. I like the color and material. I did have a little issue with setting the date. The day is in English and Chinese. That's a first, lol. It's usually in English and Spanish. It would be a nice gift for a youngster to learn military time.

Broke within first 3 month

Color: B-Green 2

I wore it for work due to no clock and not being able to look at phone on the clock. Instead of relying on managers to tell me the time and so on I bought this. Was quite reliable until I dropped it a few times then one day I could only tell time through the minute hand. Had to replace it with a digital because I do not trust a mechanical one at the moment due to this. Also the glow barely worked, it'd glow but not bright enough to tell time and not for long. I'd say I guess you get what you pay for although it should withstand dropped better internally. Durability sucks and comfort was there.

Nice looking, but Will Not Keep Time!

Color: C-Black Luminous 2

This is my second watch from this company. This was a different style! The first one ran perfect for 3 years! So I brought another one. This one, out of the box was slow. I changed the battery, still, slow! I even brought a second one from them, it too is running slow.

Good buy

Color: A-Green Luminous

OK, This is a inexpensive watch. I bought this watch as an every day work watch not a dress watch. I have worn it for several months and this is what I have experienced. It is comfortable to wear. It is lite and compact. The strap is comfortable and durable. I have gotten it wet and it has not been effected. When I got it I synchronized it with an atomic clock, it has kept perfect time. I have read other reviews that stated it did not keep good time, this has not been my experience. The dial is easy to read even in low light. the fact that other buyers have had some issues leads me to believe the manufacture my have lacks quality control. Over all, for $20 I have found it to be a good value. I would have given it 5 stars; but battery life remains to be seen.
