This is a retired professional tool watch ref 1665 Seadweller and was purchased from the original owner. It has spent its life as a dive tool and its been well used. It was born as a double red Seadweller. The case is in excellent vintage condition and very thick with fully visible numbers at 6 and 12 - The original owner stated that the original dial was swapped out by Rolex at service in the late 70s. The dial is not a service dial. It is just not original to this watch. Also the caseback was replaced at service as well. The bracelet is the original 9315 and the amazing ghost insert owner believes was original as well. The movement is running strong and keeping excellent time.
