I am quite a newbie at this forum. I was hoping that you could share with me some of your knowledge of watches. I have a piece that I cannot find anything on. It seems unique so far...cannot find another. I have Searched for hours upon hours for something even remotely close and have had no luck. The item is a very large sunburst style brooch with the spokes of the burst being 14K white gold and then there are 18K yellow gold twists around these. Scattered throughout the design are diamonds (unsure if CZ or the real deal) In the very middle is a watch that is marked ETERNA then at the bottom of the face Birks and under that SWISS. There is also a mark on the back of the brooch that reads Birks 18K. The back of the watch is marked with what looks to be a square with an L inside followed by 14K. When you remove the back of the watch, it shows ETERNA and a number 5217149.
I am aware of the Company Birks, but beyond that, I have found nothing. I can upload pictures if this will help
