Is it in running condition? These bring a lot more than not running. Gruen is among the more desired older watches. The men's watches seem to bring more than the ladies model. Yours appears to have an original "band". If it's running, keeping time and with the case being gold filled, on Ebay it should bring $25 - $50. If not running.........wel l......most jewelers nowadays charge $60 to clean and adjust. At least that was the price a few years ago.
