16550, 16570, 216570
1985 - Present
Rolex originally only offered the Explorer II with a black dial; however the release of the reference 16550 also marked the introduction of the white dial option to the Explorer II line of watches, and collectors began referring to white dial variants as "Polar" Explorers. As the Explorer lines of watches are designed for adventurers and use outdoors, the "Polar" nickname is fitting for the version with the white dial. Other than dial and hand colors, there is nothing separating a "Polar" Explorer from a regular Explorer II with a black dial. However, the simple change in dial color results in a remarkably different looking watch.
