1991 Rolex Explorer II (Ref. 16570) Box, Papers, RSC Service Card

Rolex Explorer 2 16570
The Rolex Explorer II Ref. 16570  was introduced in 1989 and was the predecessor to the Rolex Explorer II ref. 16550. The Rolex Ref. 16550 and Ref. 16570 look very similar but do have some big differences. The Explorer II reference 16570, featured a newer type of movement the caliber 3185 and later the 3186 which offered the jumping hour hand. 
This specific Ref. 16570 has been recently serviced and is running flawlessly. The black dial and fixed stainless steel bezel are not only handsome in looks but also extremely functional. The cal. 3185 movement with its jumping hour hand and accompanying GMT hand make this an ideal piece for the frequent traveler as its easy to set and track dual time zones. The black dial makes a statement without being overly flashy and it looks just as good on its Ref. 78790A Oyster bracelet as it does on a leather strap or nylon Nato.
