Rolex Explorer II 42 mm 216570BLK Steel Black Rolex Explorer II 42 mm 216570BLK Steel…

The Rolex Explorer II is one of the most purposeful and storied sport watches in the brand's lineup, originally introduced to serve the needs of cavers, volcanologists, and scientists working in environments where distinguishing day from night was a matter of safety. The 216570 generation — introduced in 2011 — brought the case diameter to a commanding 42mm, giving it a bold, modern wrist presence while honoring decades of exploration heritage. The 216570BLK variant, with its striking black dial, is the darker and arguably more dramatic of the two dial offerings in this reference, appealing to collectors who want a tool watch with genuine character.

The Explorer II 216570 has a 42mm steel Oyster case and a fixed steel bezel engraved with 24-hour graduations. The orange 24-hour hand can indicate a second time zone or distinguish day from night.

The black dial has luminous geometric hour markers and Mercedes-style hands. Its orange 24-hour hand is read against the graduated outer steel bezel. The date window sits at three beneath the Cyclops lens.

Rolex specifies the self-winding calibre 3187 for the Explorer II reference 216570.

The steel Oyster bracelet has three-piece links and a folding Oysterlock safety clasp.
