This is an example of the Yankee Clipper. This was an awful and filthy looking watch but came out amazing after a deep clean and service. The case is yellow gold plate with a stainless steel back. It has the scalloped edge which is hard to see in the photos. Date code is M5. The movement is a 17J 11ALAC also with a M5 date code. Perfect dial with yellow gold applied hour markers.
Case Serial No.
