I have a 21 Jewel 18K Yellow gold mesh band with 18K white gold case. It has 22 round diamonds around the face. Multiple hand scribed markings inside the back cover as well as the bucherer "lady" stamp, stamp of 18K 0.750, looks like a 202 stamp. The watch assembly itself has 4 ADJ, Bucherer, Jewels 21 stamped on it as well as SWISS and a + - it by a purple hour glass gem. I see 6 purple gems including the hour glass one. I have plenty of photos I can post as well. I'm unable to post but can work out a link if needed.
Thanks for any help!!
