Rolex Oyster Perpetual Air-King, Reference 126900-0001

Rolex has launched a new-generation Oyster Perpetual Air-King watch. The new model (reference 126900-0001) features a completely redesigned case with a crown guard and straight sides like the majority of Professional category models. The proportions of the Oyster bracelet have also been revisited, and notably the centre link has been broadened. In a first for the model, it is equipped with an Oysterlock safety clasp.

The Oyster Perpetual Air-King watch’s display has also been refreshed and is perfectly balanced thanks to the addition of a ‘0’ before the ‘5’ on the minutes scale. Each five-minute interval is, therefore, now marked by two digits.

The optimized Chromalight display guarantees maximum legibility in dark conditions. The hands and triangular hour marker at 12 o’clock are filled or coated with a new luminescent material that provides a long lasting intense glow. The 3, 6 and 9 numerals, which were previously made entirely from 18 ct white gold, are now also visible in the dark thanks to this innovative material, which is exclusive to Rolex.

The 40 mm Oyster case of the new-generation Air-King has a waterproof to a depth of 100 metres (330 feet). Its middle case is crafted from a solid block of Oystersteel. The hermetically screwed down case back is edged with fine fluting. The Twinlock winding crown is fitted with a double waterproofness system and protected by an integral crown guard. The crystal is made of scratchproof sapphire with antireflective coating.

The new-generation Air-King is equipped with the self-winding calibre 3230. Entirely developed and manufactured by Rolex, Calibre 3230 incorporates the patented Chronergy escapement, 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.

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, patented high-performance Paraflex shock absorbers, increasing the movement’s shock resistance. Thanks to its barrel architecture and the escapement’s superior efficiency, calibre 3230 provides an exceptional power reserve of approximately 70 hours.

The Oyster bracelet on this new watch features the Rolex-designed, 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.

Like all Rolex watches, the Oyster Perpetual Air-King is covered by the Superlative Chronometer certification redefined by Rolex in 2015. It has an exceptional precision of −2 /+2 seconds per day. 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.
