Gruen Precision, circa 1960's

Fine looking men's watch. The mechanical 510CA movement is running well and keeping good time. It has been cleaned within the past year. The case is base metal with a stainless steel screwback. The crown and crystal are new. The caseback is inscribed 'water and shock resistant' but as with all vintage watches, water should be avoided! The case is 34mm wide and 40mm lug to lug. The dial is in very good condition and includes luminescent hour and minute hands.
