The Rolex Explorer II 226570 was released in 2021 to mark the model’s 50th anniversary, this latest iteration features refined proportions, an updated movement, and enhanced legibility while maintaining the distinctive dual-time functionality that defines this professional tool watch. The bezel maintains its brushed stainless steel appearance with recessed, and blackened, 24-hour graduations. This is a style that dates back to the original Explorer II 1655 from 1971, later evolving with the 16570.
