Looks really good.
Color: 6638: Gold band & Gold dial
Looks great, quality is really good too. Only downfall is that if you don't wear it everyday, you will have to wind it up and move it to get the second hand moving again and then set the time again i can get mine sit for a whole day without resetting time but by day two it has to be reset. Even with that, it's a great watch. Have gotten lots of compliments.

Beautiful, but doesn’t last
Color: 9910: All black
It’s beautiful, but does not last. Purchased as a gift for my husband and it stopped working altogether and wasn’t able to be wound after a few weeks. We returned it. He really missed having it so we ordered a new one, hoping to have better luck. This one lasted a few months but the needle for then”Day of the week” has since fallen off today. Very disappointing.
