Rolex Explorer II watches were developed with adventurers in mind and are noted for their toughness and resistance to extreme situations. We compared two editions of the "Polar" dial Explorer II: the ref 216570 has a bigger 42mm casing, a white face, and an orange GMT arrow hand. Meanwhile, the ref 16570 is the ref 216570's predecessor, featuring a 40mm case and a white dial with a red 24-hour indicator.
