The Rolex Explorer II 16570 is a versatile watch in that it can be easily worn as an everyday watch if your style is more casual or sporty. However, thanks to its practical GMT display with two time zones, the Rolex 16570 makes for a great adventuring and traveling watch too. While all 16570 watches have stainless steel cases and bracelets, there is a choice between a sleek black dial or a fresh Polar white dial. Plus, since the reference 16570 was in production for quite a long time, you can choose between earlier models with tritium lume and lugs holes that look more vintage or later models with Super-LumiNova and engraved rehauts for a more modern look.
