This is an amazing example of the highly desirable “panda” dial (white with black registers) Hamilton Chrono-Matic from the 1960s. These watches utilized the same movements as some of the automatic Heuer Autavias, the famous Calibre 11. This Chrono-Matic is in incredible condition. The case is unpolished and sharp, with normal wear. The dial is flawless, with no wear. Finally, the original tritium lume is present on both dial and hands, aged to a golden yellow.
