The Explorer models embody the privileged relationship that has always bound Rolex and exploration. Since the late 1920s, Rolex has been using the world as a proving ground to test its watches under real-life conditions, in the quest for greater precision, robustness and reliability.
A scratch resistant sapphire crystal, a clear dial and special luminescent markings allow the rugged Rolex Explorer II to be read even in the most challenging conditions, while its trademark orange 24-hour hand helps polar and underground adventurer differentiate between daytime and night time hours without the reference of the sun.
An independent hour hand, which provides a second zone function in conjunction with the fixed, or “home”, 24-hour display, and an integrated Cyclops lens that magnifies the date, are other functions that make the Explorer II highly appreciated by global adventurers.
The Explorer II is equipped with an additional 24-hour display; a dedicated hand circles the dial in 24 hours rather than the usual 12, pointing to a fixed bezel with 24-hour graduations. This function enables the wearer to distinguish the hours of the day from the hours of the night, an essential feature for those who venture into environments where darkness reigns supreme such as in the depths of caves, or where the sun never sets like the polar regions in summer.
The Rolex Explorer benefited from experience gained in the Himalayas, acquiring its clearly distinctive hour and minute hands and its landmark, highly legible black dial with luminescent indices and large Arabic numerals at 3, 6 and 9 o'clock. It is designed for optimal legibility even in the dark.
Rolex uses Oystersteel for all its steel watches. This high-performance alloy is mainly used in the high technology, aerospace and chemical industries, where maximum resistance to corrosion is essential. Oystersteel is extremely resistant and highly polishable. It maintains its beauty even in the harshest environments.
The high-contrast, Chromalight display innovates by pushing the boundaries of visibility in dark environments. The blue glow of the hour markers and hands lasts up to eight hours with a uniform luminosity throughout, practically twice as long as that of standard luminescent materials.
