if you are a case nerd then this one is for you ......one of the sharpest unmolested cases we have uncovered on a 5513 from the late 80s - The dial patina has aged unevenly and the hands match the darker patina lume plots. The surface of the dial has begun to evenly turn to a matt finish as well. The serial and ref number are easily readable between the lugs. The insert is original and in perfect condition as is the bezel. The bracelet is tight and has all links. The movement is running and keeping excellent time however the last service is unknown.
