I bought this OLEVS automatic as a gift for my husband and he was thrilled. The gold-tone finish is rich and consistent, the open-heart dial showing the movement is a beautiful touch, and the day/week sub-dials work smoothly. The caseback shows the automatic movement clearly — you can see the rotor spinning with every wrist movement. It feels comfortable and the bracelet is solid. For the price, this is an outstanding piece. He gets compliments every time he wears it.

Great Mechanical Self-winder

Color: Black

Wow! So far I have only adjusted the time three times over the last few months. So far It keeps great time and looks good. Well worth the money after having blown a few dollars on less expensive mechanical watches that fail after only a few months of use. This thing is very good!
