This is a great example of the highly desirable “panda” dial (white with black registers) Hamilton Chrono-Matic from the 1960s. This example is in lovely condition, with an unpolished case, and original signed crown. The dial shows some age consistent with wear, but is overall very well preserved, and most of the distortion can be attributed to clouding/light scratches on the original crystal. The lume on the dial and hands is perfect, original, and in-tact.
