Rolex Oyster Perpetual Explorer

Rolex is presenting its new-generation Oyster Perpetual Explorer. At 36 mm, it returns to the size of the original model launched in 1953 following the first ascent to the summit of Mount Everest by Sir Edmund Hillary and Tenzing Norgay on 29 May that year.

The new-generation Explorer is notably released in a yellow Rolesor version (combining Oystersteel and 18 ct yellow gold). The black dial, now lacquered, bears the index hour markers and emblematic 3, 6 and 9 numerals that are the cornerstones of the model’s personality, evoking the determination and spirit of adventure that give rise to great achievements.

The new-generation Explorer’s Chromalight display is particularly impressive. 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 is equipped with calibre 3230, a movement at the forefront of watchmaking technology.

Like all Rolex watches, the Oyster Perpetual Explorer carries the Superlative Chronometer certification, which ensures excellent performance on the wrist.

AN EXPLORATION TOOL 

Presented in 1953, the Explorer is emblematic of the close ties between Rolex and exploration. In the 1930s, the brand began to equip numerous Himalayan expeditions with Oyster watches. Among these was the group that Sir Edmund Hillary and Tenzing Norgay were part of when they became the first to reach the summit of Mount Everest, at 8,848 metres (29,028 feet).

This pioneering move illustrated the company’s ambition to use the world as a laboratory, testing its watches in real conditions in order to continually improve them. The feedback that Rolex received from the members of these different expeditions therefore had a direct influence on the evolution of its watches, making them more precise and robust. 

ROLESOR, A MARRIAGE OF GOLD AND STEEL

Rolesor, the combination of 18 ct gold and Oystersteel on a Rolex watch, has been a signature feature of the brand since 1933, when the name was registered. It is a meeting of two metals: one, noble and precious, attractive for its lustre and stability; the other, highly resistant to corrosion, assuring strength and reliability. All of these qualities mirror the elegance and performance that come together in a Rolex watch.

On the yellow Rolesor version of the new-generation Explorer, the bezel, winding crown and centre links of the bracelet are in 18 ct yellow gold, while the case and outer links of the bracelet are in Oystersteel.

THE OYSTER CASE, SYMBOL OF WATERPROOFNESS

A paragon of robustness and reliability, the new-generation Explorer’s 36 mm Oyster case 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, screws down securely against the case. The crystal is made of virtually scratchproof sapphire. The waterproof Oyster case provides optimum protection for the watch’s movement.


PERPETUAL CALIBRE 3230
The new-generation Explorer is equipped with calibre 3230, a movement entirely developed and manufactured by Rolex that was released in 2020. 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 3230 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 3230 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 3230 extends to approximately 70 hours.

OYSTER BRACELET AND OYSTERLOCK SAFETY CLASP

The new-generation Explorer 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. 


SUPERLATIVE CHRONOMETER CERTIFICATION
Like all Rolex watches, the Oyster Perpetual Explorer 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.
