Simply super RED Sub from 1972. The dial and hands are flawless with nice patina. The case is worn well but unpolished and all numbers clear. The bezel is sharp and the insert is uniformly faded to a very cool grey blue. The bracelet is the original 9315/380 with full links plus diver extension and has some moderate stretch commensurate with age. Comes with box and oyster manual. Movement is running strong and keeping excellent time. Last service unknown.
