Rolex presents a new-generation Oyster Perpetual Explorer II with a redesigned Oystersteel case and bracelet. The new model, Rolex Explorer II 226570 comes with a 42mm case and white lacquer dial dial.
The watch features black PVD coated hour markers, while 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. In daylight, these display elements also have a brighter white hue.
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.
Waterproof to a depth of 100 metres (330 feet), the 42mm diameter Oyster case incorporates an Oystersteel middle case and hermetically screwed down and fine fluted caseback.
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 made of virtually scratchproof sapphire glass has a Cyclops lens at 3 o’clock for easy reading of the date.
The new-generation Explorer II houses calibre 3285, entirely developed and manufactured by Rolex. Thanks to its barrel architecture and the escapement’s superior efficiency, the power reserve of this self-winding mechanical movement extends to approximately 70 hours.
The Rolex Explorer II 226570 comes with an Oyster bracelet with the patented Oysterlock folding safety clasp and Easylink comfort extension link. In addition, a concealed attachment system ensures seamless visual continuity between the bracelet and case.
Like all Rolex watches, the Oyster Perpetual Explorer II is covered by the Superlative Chronometer certification redefined by Rolex in 2015.
