I really like the art deco watches of yesteryear and recently picked up a match to a Lucian Piccard I got a year ago. They are both 14k gold, 33mm cases and have fun and unique markers on the dial. One has blue markers with silver dial and the other has black markers on a gold dial. It appears the crown has been replaced on the black marker watch. I purchased new LP straps for them on Ebay and the blue came with box and paperwork and I purchased a box for the black.
Two years ago I saw a similar watch with green markers on Ebay that was branded Blancpain on the dial but the seller wanted over $2k for it and I couldn't justify spending that much. I've searched Google but have never been able to find pictures of it since.
I think these are probably 1950's or 60's and according to Google the time frame of the art deco period was 1920-30's but if you have a vintage watch that is art deco in your opinion and would like to share it, please post pictures for all to enjoy.
