The Rolex Air-King reference 116900, introduced in 2016, represents a distinct departure from previous Air-King models, adopting a more robust and visually striking aesthetic. This reference integrates design elements reminiscent of Rolex's professional instrument watches, particularly with its unique dial layout that features prominent minute markers alongside the traditional hour markers. It stands out within the Oyster Perpetual collection for its specific design language and technical specifications, offering a contemporary interpretation of a long-standing model line.

This reference features a 40mm Oyster case crafted from Oystersteel, a proprietary stainless steel alloy known for its durability and resistance to corrosion. The case is fitted with a fixed smooth bezel and a screw-down crown, ensuring water resistance to 100 meters. Powering the watch is the automatic Caliber 3131, a COSC-certified chronometer movement equipped with a Parachrom hairspring for enhanced shock resistance and magnetic field protection, providing a power reserve of approximately 48 hours. A sapphire crystal protects the dial.

The Air-King 116900 appeals to collectors seeking a modern Rolex with a distinctive character. Its unique dial, featuring a combination of large Arabic numerals for the 3, 6, and 9 o'clock positions and prominent minute markers for the remaining hours, sets it apart from other Rolex sports models. The green Rolex logo and seconds hand, along with the yellow coronet, add subtle color accents. This reference was produced until 2022, making it a relatively recent yet discontinued model within the brand's history.
