This watch obviously was serviced and cared for in its lifetime. The case has some light scratches throughout. All edges are sharp and distinct. The case back writing is only barely visible in a few areas under magnification. The dial and hands are in very good condition. (see pictures for details) The hands have developed a light patina. The lume on the hands, dial, and the internal rotating bezel all match in color. The crystal very good vintage condition. The dial has gained a very nice soft patina in the center with a lovely grey edge with the rotating inner bezel. The Lume is mostly consistent on the indexes, hands, and the top of the inner rotating bezel. The cross-hatched crowns appear to be original to the watch. This is an excellent example of an original well cared for Hamilton Super Compressor 600. Exact service history is undocumented.
