Rolex is introducing a new Oyster Perpetual Air-King, a watch that perpetuates the aeronautical heritage of the original Rolex Oyster. The new Air-King epitomizes Rolex’s privileged ties with the world of aviation during its golden age in the 1930s. The Air-King’s Oyster case, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness. Its characteristically shaped middle case is crafted from a solid block of particularly corrosion-resistant 904L steel.
It features a distinctive black dial with a combination of large 3, 6 and 9 numerals marking the hours and a prominent minute scale for navigational time readings. The dial bears the name Air-King in the same lettering that was designed specially for the model in the 1950s. The fluted case back is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. Fitted with the Twinlock double waterproofness system, the winding crown screws down securely against the case. The crystal is made of virtually scratchproof sapphire. The waterproof Oyster case provides optimum protection for the Air-King’s high-precision movement and is also fitted with a shield to protect against magnetic fields, a feature of pilots’ watches of the past.
The Air-King carries the Superlative Chronometer certification redefined by Rolex in 2015, which ensures singular performance on the wrist.
New Air-King is equipped with calibre 3131, a self-winding mechanical movement entirely developed and manufactured by Rolex. Its architecture, manufacturing quality and innovative features make it singularly precise and reliable. The oscillator, the true heart of the watch, has a blue Parachrom hairspring patented and manufactured by Rolex in an exclusive alloy. Insensitive to magnetic fields, the Parachrom hairspring offers great stability in the face of temperature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks. It is equipped with a Rolex overcoil, ensuring its regularity in any position.
The escapement features a paramagnetic escape wheel made from a nickel-phosphorus alloy produced via UV-LiGA (micromanufacturing by electroforming). Calibre 3131 is equipped with a self-winding module featuring a Perpetual rotor and offers a power reserve of approximately 48 hours.
The Air-King is fitted on a solid-link Oyster bracelet in 904L steel with a folding Oysterclasp. This bracelet features the ingenious Rolex-patented Easylink rapid extension system that allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.
