The Rolex Explorer II Reference 16570 holds a significant place in the brand's history, representing an evolution of the iconic Explorer collection. Introduced in 1989, the Reference 16570 replaced its predecessor, the Reference 16550. The production of the Rolex Explorer II Reference 16570 spanned over a decade, ending in the mid-2000s.
The main difference justifying the new reference number was an upgraded movement cal. 3185. Subsequent editions of this reference saw enhancements like Luminova, a laser-etched reheaut and the no-holes case.
