1975 Ghost Red Submariner 1680 with great patina

A super nice red sub from 1975 close to the end of the red submariner production series. The dial is very nice with a little aging which is common and the hands match well. The case is polished in the past however remains thick and even. The bezel is a little worn and the insert is a very nice grey ghost mk3 in nice shape . The bracelet is a 9315/380 with 11 links plus diver ext. The movement is running strong and keeping excellent time however last service is unknown.
