This Rolex Explorer II Ref. 216570 “Orange Arrow” is a modern classic designed for adventure and extreme environments. Featuring a robust 42 mm Oystersteel case, this reference is distinguished by its bold orange 24-hour hand, a tribute to the original 1971 Explorer II. The crisp dial ensures exceptional legibility with Chromalight luminous markers, while the fixed 24-hour engraved bezel allows tracking of a second time zone and distinguishing day from night. Powered by the Rolex Caliber 3187 automatic movement, the watch offers outstanding precision, Paraflex shock absorbers, and a power reserve of approximately 48 hours. The durable Oyster bracelet with Oysterlock clasp ensures comfort and security. This discontinued reference, offered mint and full set, represents one of the last Explorer II models with the iconic orange arrow, making it highly desirable for collectors and enthusiasts alike.
