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 radical 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 and the bezel font was slightly modified from the previous reference. 

CASE & BRACELET

The excellent case features very thick lugs that retain crisp chamfers while remaining symmetrical in shape with very minimal evidence of previous polishing and honest signs of light use. The original fixed 24-hour stainless steel bezel is in extremely crisp and potentially unpolished condition, showing gentle signs of use with the factory black enamel remaining fully intact. The case back retains its original green Rolex factory sticker. The original Rolex 78790 Oyster bracelet with 501B end pieces retains 11 links that show virtually no stretch and will fit up to a 7-inch wrist. 

DIAL & HANDS

The original glossy black dial with white gold surround markers is in flawless condition, with no age or damage present. The tritium lume plots exhibit no degradation when inspected under UV light with no notable patina present. The original tritium hands match the dial perfectly with no degradation present under UV light inspection.

ACCESSORIES 

The watch comes complete with its original inner and outer boxes, Rolex guarantee paper, Rolex calendar, and booklets. The watch is keeping time perfectly, backed by a 1-year warranty on accurate timekeeping.
