Rolex followed up the Explorer II ref. 16550 with the ref. 16570 in 1989.
It kept its 40mm size and stainless steel Oyster case and Oyster bracelet design.
New to the dial was the black outlines of the hour markers and against the cool white dial, the luminescent indexes really pop up. It is so called Polar!
Also new to the Polar ref. 16570 was the movement. Early models of the 16570 are equipped with the Caliber 3185 automatic movement, while later versions are powered by the Caliber 3186. Also found on the later versions of the ref. 16570 is the “ROLEX ROLEX ROLEX” engraving on the rehaut as an anti-counterfeit measure.
This particular ref. 16550 dates back to 1997/1999 so it’s powered by the Caliber 3185 and does not included the rehaut engraving.
Whether opting for a new vintage or the Explorer II Polar, these Rolex sport watches are a real take two.
Robust stainless steel coupled with a cool white dial and a bright 24-hour hand makes for a timeless sports watch that brings out one’s adventurous side.
Both exceedingly practical thanks to its time, date, and GMT-hand functions, and impeccably designed, the Explorer II Polar is a Rolex not to be missed.
