Rolex Explorer II 42 mm 226570PVD Steel/PVD/DLC Black Rolex Explorer II 42 mm 226570PVD Steel/PVD/DLC…

The Rolex Explorer II has been a cornerstone of Rolex's professional sports-watch lineup since its introduction in 1971, originally conceived for speleologists and adventurers who needed to distinguish between day and night hours deep inside caves or in polar regions where sunlight is continuous. The 24-hour graduated fixed bezel — one of the model's most iconic design signatures — fulfills that mission precisely, and it remains the defining visual element of every Explorer II produced to this day. Reference 226570 represents the current-generation Explorer II, enlarged to a commanding 42mm case diameter that gives the watch substantial wrist presence without sacrificing the purposeful, legible character that made the line famous.

The example offered here by Bizak & Co. carries the designation 226570PVD, denoting that the stainless steel case and Oyster bracelet have been treated with a PVD/DLC (Physical Vapor Deposition / Diamond-Like Carbon) coating. This process bonds an extremely hard, thin layer of carbon-based material to the metal surface, producing the deep matte-black finish visible across the case, lugs, bracelet, bezel, and crown. The result is a watch that reads as stealthy and modern while retaining every millimeter of Rolex's original architecture — from the screw-down Triplock crown to the solid-link Oyster bracelet that has been protecting Rolex movements for decades.

The black dial on this reference is a natural complement to the dark case treatment. Luminous dial markers ensure legibility in low-light environments, honoring the Explorer II's heritage as a tool watch meant to perform in demanding conditions. The large 24-hour hand sweeps the same path as the standard hour hand but completes one revolution in 24 hours, allowing the wearer to read a second time zone or simply confirm AM versus PM at a glance — a practical complication that pilots, expedition leaders, and frequent travelers have long appreciated.

Powering the watch is a Rolex automatic movement, providing the reliable self-winding performance that Rolex calibers are renowned for worldwide. The case is rated to 100 meters (330 feet) of water resistance, consistent with Rolex's Oyster case standard and more than adequate for everyday wear, swimming, and recreational diving in shallow water. The screw-down crown reinforces that seal, ensuring the movement remains protected from moisture and dust in any environment the wearer is likely to encounter.
