Great for everyday wear, vibrant dial, comfy band, no locking crowns. Would buy again.
Color: 6638: Gold band & Green dial
Excellent price point, stylish, and the pictures match what you get. The green is bright and vibrant and the gold band looks real although stainless. A great piece to wear all the time without worrying about losing value. Would buy again. My biggest complaint: The small crown do not lock so they get randomly hit and cant be trusted. The time kept is fine but do no expect to be able to lock the days in. The crown wont spin to lock them.

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.
