1991 Rolex Explorer II (Ref. 16570) "Polar" Dial

It seems as though every reference and iteration of the Rolex Explorer II has details that set them drastically apart from one another, making it the Rolex reference that has seen the most drastic evolution through its tenure. From the first and original "orange hand" matte dial ref. 1655, to the modern 42mm produced today and everything in between.

The Rolex Explorer II ref. 16570  was introduced in 1989, directly succeeding the transitional ref. 16550 with some subtle cosmetic and internal upgrades. The Rolex Explorer II ref. 16570 employs the updated and robust cal. 3185 jumping hour movement, the black paint on the hands and marker surrounds is now standard on the white or “polar” dial variants, and the bezel font has been slightly modified from the previous reference.

The original white dial with black marker surrounds is flawless, showing no age or damage. The tritium lume plots are bright with a subtle eggshell color, and exhibit no degradation when inspected under UV light. The original tritium hands match the dial with no degradation present under UV light inspection.


None. The watch is keeping time perfectly, backed by a 1-year warranty on accurate timekeeping.
