Rolex Explorer II Ref. 16570

The Rolex Explorer II Ref. 16570 is one of the most purposeful and understated professional models in the modern Rolex catalogue, originally conceived for explorers, spelunkers, and polar expeditions where day and night can blur into one. Produced from the late 1980s through 2011, the 16570 represents the final evolution of the classic 40 mm Explorer II before the jump to the larger 42 mm case, making it especially appealing to collectors who value balanced proportions and traditional tool-watch design.

This example features the black dial configuration, offering a crisp, high-contrast layout with applied luminous hour markers, Mercedes hands, and the signature red 24-hour hand—a defining aesthetic of the Explorer II line. The fixed brushed stainless-steel bezel is engraved with a 24-hour scale, allowing the wearer to track a second time zone or distinguish day from night at a glance. The matte black dial lends the watch a purposeful, no-nonsense appearance, reinforcing its origins as a true expedition instrument rather than a dress-leaning sports watch.

Housed in a 40 mm Oystersteel case, the Ref. 16570 wears exceptionally well thanks to its slim profile and clean case geometry. It is paired with the correct Oyster bracelet (Ref. 78360), featuring solid links and a folding Oysterlock clasp, delivering both comfort and durability. The brushed finishing throughout emphasizes its tool-watch DNA while remaining versatile enough for everyday wear.

Powering the Explorer II is Rolex’s automatic Calibre 3185 or 3186 (depending on production year), a COSC-certified movement renowned for reliability and precision. The independently adjustable GMT hand allows seamless local time changes without stopping the movement—an invaluable feature for frequent travelers. With 100 meters of water resistance, sapphire crystal, and robust construction throughout, the 16570 remains every bit as capable today as when it was first issued.

The Rolex Explorer II Ref. 16570 is increasingly recognized as a modern classic—offering authentic professional heritage, timeless aesthetics, and exceptional wearability. For collectors seeking a Rolex sports model that flies under the radar while delivering genuine pedigree, the 16570 stands as one of the most compelling and honest tool watches the brand has ever produced.
