The call of the peaks
The Oyster Perpetual Explorer 40 in Oystersteel features a distinctive black dial with characteristic 3, 6, and 9 numerals with a Chromalight display.
Optimal legibility in any situation
The dial is the distinctive face of a Rolex watch, the feature most responsible for its identity and readability. The Explorer model’s characteristic 3, 6 and 9 numerals are filled with a luminescent material emitting a long-lasting blue glow, like the hour markers and hands.
Like all Rolex timepieces, the Explorer 40's dial is designed and manufactured in-house, largely by hand to ensure perfection.
An established icon
The Oyster Perpetual Explorer 40 imparts a fresh elan to the sober, clean lines that have long established it as an icon.
The smooth bezel in Oystersteel is robust yet elegant, and in perfect harmony with the Explorer’s iconic heritage.
Highly resistant to corrosion
Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential.
Oystersteel is extremely resistant, offers an exceptional finish once polished and maintains its beauty even in the harshest environments.
The Oyster bracelet
Alchemy of form and function
The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology, designed to be both robust and comfortable. It is equipped with an Oysterlock folding clasp, which prevents accidental opening and the Easylink comfort extension link, also exclusive to Rolex.
This ingenious system allows the wearer to increase the bracelet length by approximately 5 mm, providing additional comfort in any circumstance.
