Ladies wind up Gruen Precision

I acquired this beautiful piece of history from a Goodwill 2 years ago. It was mixed in with 13 other watches and pieces of misc jewelry. It's a wind up and it works. I love this piece. It's a 10K RGP (Rolled Gold Plated) Bezel and it still has the original Speidel elastic band with the patent #2689450 and on the end of the band it reads 10K.G.F (Gold Filled) TOP CAPS 63 Stainless St 80 CAPS. I'm honored to be taking care of this piece.
