Built for extremes, worn across continents—the Rolex Explorer II is a tool watch with real world mileage. This 40mm reference 16570T features a sharp black dial with luminous hour markers, a bold 24 hour hand, and that steel bezel that’s become its signature. Originally designed for spelunkers and polar expeditions, the 24 hour scale helps distinguish day from night in the most unforgiving conditions. The solid Oystersteel case and automatic movement speak to Rolex’s enduring reliability, while the understated design makes it as relevant in the city as it is on the trail. Purposeful, iconic, and adventurous.
