Introduced in 2011, the Rolex 216570 Explorer II represents a significant evolution of a model with deep roots in exploration-oriented horology. Crafted from robust 904L Oystersteel, the 42mm case size distinguishes this reference from its forebears, offering presence and legibility prized by seasoned collectors. The hallmark white 'Polar' dial is paired with distinct black-outlined hour markers and an orange 24-hour hand, a nod to the original 1971 ref. 1655. Powered by Rolex's in-house Caliber 3187, the movement features a Paraflex shock absorber and a blue Parachrom hairspring, demonstrating a focus on practical durability and precise timekeeping even in the harshest conditions. Its fixed, engraved 24-hour bezel and independently adjustable hour hand provide true GMT and dual time capability—essential for both explorers and frequent travelers. The dial's innovative Chromalight display ensures outstanding legibility in any light. Highly regarded as the last of the non-Cerachrom bezel Explorer IIs, the 216570 occupies a unique intersection of modern Rolex engineering and classic tool-watch aesthetic. It became a standard bearer among collectors for adventure-ready functionality, subtle yet distinctive design, and technical reliability. As of 2021, the 216570 was replaced by a new-generation Explorer II, cementing its status as a modern classic. Like New with Rolex box and papers dated 2020.
