This watch is awesome. I love the art deco look. A few things about this watch. You wind and then shake it up and down or side to side. It will keep good time. I thought the band didn't work but I just didn't know how to use it. You use the little button to make it slide the band up and down. It is marked 10k gold filled on the back and it's marked 1-20-12k gold filled on the band's slider. Any questions please ask me. Ships USPS priority mail. Pre owned.
