The Rolex Oyster Perpetual Explorer II reference 216570 combines a 42 mm Oystersteel case with a high-contrast black dial, a fixed 24-hour graduated bezel and a three-piece Oyster bracelet. Its distinctive orange arrow-shaped hand works alongside the bezel to distinguish daytime from night-time hours or display a second time zone.
Introduced in 2011, reference 216570 marked a major evolution of the Explorer II with an enlarged 42 mm Oyster case, expanded dial proportions and a prominent orange 24-hour hand inspired by the visual identity of the original Explorer II.
The black dial uses oversized geometric hour markers and broad hands for immediate reading. Chromalight luminescent material produces a long-lasting blue glow, while the orange arrow-shaped hand introduces a clear contrast across the display.
The fixed Oystersteel bezel carries a complete engraved 24-hour graduation. Used with the additional hand, it allows the wearer to distinguish daytime from night-time in environments where natural light is absent or display a second reference time.
The three-piece Oyster bracelet continues the functional character of the case. It is secured by a folding Oysterlock safety clasp and incorporates an Easylink extension that allows the bracelet length to be increased by approximately 5 mm.
Oversized hour markers and broad hands are filled with Chromalight material, providing a long-lasting blue luminescent display in reduced light.
The fixed Oystersteel bezel features an engraved 24-hour scale designed for distinguishing daytime from night-time or reading a second time zone.
The self-winding mechanical movement incorporates a Parachrom hairspring and Paraflex shock absorbers while providing an approximate 48-hour power reserve.
The conventional hour hand can be adjusted independently in one-hour increments without interrupting the minutes, seconds or 24-hour reference-time display.
A scratch-resistant sapphire crystal protects the dial, while the Cyclops lens above the date supports clear and immediate reading.
The three-piece Oystersteel bracelet is equipped with an Oysterlock safety clasp and an Easylink 5 mm comfort extension system.
