The new Rolex Oyster Perpetual Explorer II

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 Rolex Explorer II carries the Superlative Chronometer certification, which ensures excellent performance on the wrist.
The Rolex 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.
A paragon of robustness and reliability, the 42 mm Oyster case of the new-generation Rolex 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.
