This is an amazing example of the highly desirable “panda” dial (white with black registers) Hamilton Chrono-Matic from the 1960s. This Chrono-Matic is in near-mint condition. The is unpolished and thick, with very light wear. The dial is flawless, with no marks or wear. The lume on the dial and hands is original tritium, aged to a golden yellow, with only one minor crack to the hour hand.
