Rolex Oyster Perpetual Explorer II 226570 Series

This Oyster Perpetual Explorer II in Oystersteel with an Oyster bracelet features a white dial with an arrow-shaped 24-hour hand and hour markers with a Chromalight display.

The Explorer II features a date display, an additional orange 24-hour hand and a fixed bezel with 24-hour graduations, enabling day to be distinguished from night.
