The New Rolex Explorer II
This Oyster Perpetual Explorer II in Oystersteel with an Oyster bracelet features a white dial with an arrow-shaped 24-hour hand and hour markers with a Chromalight display.
Its highly legible dial, extremely resistant Oystersteel and waterproofness have made it
the watch for the extremes.
Rolex is introducing its new-generation Oyster Perpetual Explorer II. This technical watch, in Oystersteel, was created for the boldest explorers and now features a redesigned case and bracelet. This update brings enhanced visual balance and harmony to the timepiece while remaining true to its aesthetic heritage.
On the white lacquer dial, the hour markers – whose black coating is applied using PVD (Physical Vapour Deposition)
– and the black lacquer hour, minute and seconds hands stand out for their matt finish. The 24-hour hand retains its characteristic orange hue, which is the same colour as the Explorer II
inscription that has featured on the dial since 2011.
The new-generation Explorer II also benefits from an optimized Chromalight display. In dark conditions, the intensity of the blue glow emitted by the hour markers and hands now lasts longer thanks to the innovative and exclusive luminescent material with which they are filled or coated. In daylight, these display elements also have a brighter white hue.
The new-generation Explorer II is equipped with calibre 3285, a movement at the forefront of watchmaking technology.
Like all Rolex watches, the Oyster Perpetual Explorer II carries the Superlative Chronometer certification, which ensures excellent performance on the wrist.
for the far corners
of the globe
The Explorer II is heir to the privileged relationship that has long united Rolex and exploration. Presented in 1971, this robust and reliable watch quickly became an essential tool for explorers travelling to the far corners of the globe, often in extreme conditions. Thanks to its 24-hour display comprising an additional, orange hour hand and an engraved bezel, the Explorer II allows the wearer to clearly distinguish daytime from night-time hours. This is particularly useful in areas where it is difficult or even impossible to distinguish between day and night, such as underground or in polar regions, which experience six months of daylight and six months of darkness a year. In certain conditions, this display enables the watch to serve as a compass. The 24-hour display can also be used to show a second time zone.
Distinguishing day from night
The Explorer II features a date display, an additional orange 24-hour hand and a fixed bezel with 24-hour graduations, enabling day to be distinguished from night. It became the watch of choice for speleologists, volcanologists and polar explorers. Its hour markers and hands feature a highly-legible Chromalight display with long-lasting blue luminescence.
A paragon of robustness and reliability, the 42 mm Oyster case of the new-generation Explorer II is guaranteed waterproof to a depth of 100 metres (330 feet). Its middle case is crafted from a solid block of Oystersteel, a particularly corrosion-resistant alloy. The case back, edged with fine fluting, is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement.
The Twinlock winding crown, fitted with a double waterproofness system and protected by an integral crown guard, screws down securely against the case. The crystal is made of virtually scratchproof sapphire and is fitted with a Cyclops lens at 3 o’clock for easy reading of the date. The waterproof Oyster case provides optimum protection for the watch’s movement.
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 new-generation Explorer II is equipped with calibre 3285, a movement entirely developed and manufactured by Rolex that was released in 2018 and is fitted on this model from 2021. At the forefront of watchmaking technology, this self-winding mechanical movement led to the filing of several patents, and offers outstanding performance in terms of precision, power reserve, resistance to shocks and magnetic fields, convenience and reliability.
Calibre 3285 incorporates the Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic fields.
The movement is fitted with an optimized blue Parachrom hairspring, manufactured by Rolex in a paramagnetic alloy that makes it up to 10 times more precise than a traditional hairspring in case of shocks. The blue Parachrom hairspring is equipped with a Rolex overcoil, ensuring the calibre’s regularity in any position. The oscillator is fitted on the Rolex-designed and -patented high-performance Paraflex shock absorbers, increasing the movement’s shock resistance.
Calibre 3285 is equipped with a self-winding module via a Perpetual rotor. Thanks to its barrel architecture and the escapement’s superior efficiency, the power reserve of calibre 3285 extends to approximately 70 hours.
Oyster bracelet and Oysterlock safety clasp
Alchemy of form and function
The new-generation Explorer II is fitted with an Oyster bracelet. Developed at the end of the 1930s, this three-piece link bracelet is known for its robustness.
The Oyster bracelet on this new watch features the Rolex-designed and -patented Oysterlock folding safety clasp, which prevents accidental opening. It is also equipped with the Easylink comfort extension link, developed by the brand, which allows the wearer to easily adjust the bracelet length by approximately 5 mm. In addition, a concealed attachment system ensures seamless visual continuity between the bracelet and case.
The Cyclops lens is one of the most distinctive Rolex features, and one of the most recognizable. Named after the one-eyed giant of Greek mythology, the Cyclops lens magnifies the watch’s emblematic date display two and a half times for easy reading. Behind the Cyclops, as with every feature of a Rolex timepiece, lies a history of invention, research and development, and the endless search for perfection.
Superlative Chronometer certification
Like all Rolex watches, the Oyster Perpetual Explorer II is covered by the Superlative Chronometer certification redefined by Rolex in 2015. This designation testifies that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria. These certification tests apply to the fully assembled watch, after casing the movement, guaranteeing superlative performance on the wrist in terms of precision, power reserve, waterproofness and self-winding. The precision of a Rolex Superlative Chronometer is of the order of −2 /+2 seconds per day – the rate deviation tolerated by the brand for a finished watch is significantly smaller than that accepted by the Swiss Official Chronometer Testing Institute (COSC) for official certification of the movement alone.
The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.
