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.
