Lost its quality after gaining popularity
Size: 1 count (Pack of 12)
I’ve been subscribed to this brand for at least 2 years now. It used to be heavy duty, now they switched to cheap thin carton like everyone else has. No point to overpay for average quality.

Junk!
Color: 3675 ALL Silver
Good luck getting the back plate back in once you change the battery! You get what you pay for so spend the extra money and buy a better watch not made in China.

Really nice watch!
Color: 3675 ALL Black
Really nice and clean looking watch. Fairly easy to adjust the watch band, with a little patience. Item description stated battery operated, but I don’t think it is as there is no indication that it has a battery in it. Other than that, really decent watch! I would have given it a five star rating if it were battery powered.

Great price
Color: 3675 Silver Grey
The watch looks like it should cost more than the actual price. It catches people's eye and so far it keeps accurate time. Keep in mind I've only had the watch about two weeks. Of my 10 every day watches this one is the most attractive.
