Vintage Modernist Christian Bernard Paris 22K Yellow GP Bangle Bracelet Watch Assymetric Atomic such a cool watch! mechanical, so no battery required. please wind it with a light touch and do not overwind it. it does work! such a killer MCM (mid century modern) look. Ladies wind up mechanical bangle watch made by Christian Bernard in Paris France. The watch band is a delicate 22k gold plate thin band. The watch face is assymetric, featuring a brushed gold face off to right and two layered circles to the left. Both clblack & geeen circles look to me like opaque glass. The Dial is marked Christian Bernard Paris. There are no markings on the back. Bangle is for a small to small average size wrist. Crystal in good conditions with no visible scratching or nicks. The watch runs perfectly, but will NOT be running when you receive it. You will need to wind it first.This watch does NOT have a battery. it needs to be wound daily. This watch is NOT waterproof or water resistant. This is a vintage timepiece and should be treated as such. If you have any questions or need further info, please let me know. all measurements are in the photos any questions? please ask me in the comment section below. thanks for looking, sorry no trades or holds. we ship Monday through Friday. jc
