It is 14K gold filled over stainless. It has some minor scratches normal for a vintage watch band this age. There is no plating loss that I can detect front or rear. It has been lightly polished and ultrasonically cleaned. It measures 5 and 5/8 inches or 14.5 cm in length.
With a 1 and 3/8 inch watch it should fit a 7-inch wrist. The end links measure 18.87 mm wide.
These can easily be trimmed down to fit most Accutrons with 17.55 mm lugs. There is a date stamp of 11/74 on the hasp. The buckle snaps closed nice and tight as it should. Please see the photos and determine condition for yourself.
