Outstanding Wallet
Very good Wallet Nice leather looks very nice and was easy to break in. I carry it in my front pocket and it is not to bulky. Holds a lot of card and has two pockets for cash.

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.
