Lovely Gruen Art Deco Tank Watch with filagree detail on case, approximately 30 years old. Gold plating on case is complete with no worn through areas. Crystal is also in excellent condition with only a few very light scratches. The band is original to watch and is in very good condition, however, some of the gold plating has worn off the clasp.  The case measures 28mm wide (not including stem) by 30mm tall (not including lugs).  A fresh battery has been installed and the watch keeps accurate time. Please check my feedback but don't hesitate to contact me if you have any questions.
