Break through the darkness
The Oyster Perpetual Explorer II in Oystersteel features an Oyster bracelet and a white dial, with arrow-shaped 24-hour hands and hour markers coated with Chromalight luminescent material.
24-hour outer ring
Maintain reliability in harsh environments
The Explorer II features an additional 24-hour display, with a dedicated hand that cycles the dial every 24 hours instead of the usual 12 hours and points to a fixed outer ring with 24-hour markings.
This feature allows the wearer to distinguish between day and night, which is especially important for exploring in pitch-black environments (such as deep in caves) or in areas where the sun never sets (such as during the polar summer).
White dial
Distinguishing between day and night
The Explorer II features a calendar display, an additional orange 24-hour hand, and a fixed 24-hour scale outer ring for easy day and night differentiation.
It has become the watch of choice for cave explorers, volcanologists, and polar explorers. The watch's hour markers and hands feature an easy-to-read Chromalight display that emits a lasting blue glow.
Oyster steel
High corrosion resistance
Rolex uses Oystersteel forged steel watch cases. The Oystersteel developed by the brand is a type of 904L steel. This alloy is widely used in high-tech, aerospace, and chemical industries, and therefore naturally possesses high corrosion resistance.
Oyster steel is extremely durable and shines brilliantly after polishing, maintaining its beauty even in extreme environments.
Combining form and function
The Oyster bracelet is robust and comfortable, combining style, function, aesthetics, and technology. It features an Oysterlock safety clasp to prevent accidental opening, as well as the Easylink extension system, also exclusive to Rolex.
Wearers can use this ingenious feature unique to Rolex to extend the strap by approximately 5 millimeters, ensuring comfort in any situation.
