This is a mystery as this watch was made for Buick Division of General Motors and was presented to workers who worked for GM for 25 years hard work. I don't think so. Anyway it does have the Buick logo on the dial. These were made in the 1950's. New brown leather strap.
Case is stainless steel with waterproof screw on back and screw down crown with the Rolex markings.
Band has all the proper markings and is original. Band has flip lock and is generous in size. Case back is properly marked 73090. Perfect for the person who wants the sub but not the big size. Case is stainless steel with screw on water resistant back.
