Offered here is a stunning and attractive example of a very early Rolex Explorer, Ref. 6610, circa 1957, the pre-cursor to the Reference 1016, only produced for a few years. This example is in excellent condition. The case is unpolished, with beautiful and even lugs. The dial is in great condition, with no major flaws or wear, which is difficult to find on this model. The original radium lume is present on the dial and hands, aged to a lovely orange color, with some loss to the minute hand. Overall a very attractive example of a rare and hard-to-find [in nice condition] early Explorer reference.
