Launched in 2026, the Rolex Day-Date 40 228235JG-0001 represents a fresh take on the Day-Date series, introducing a unique material known as Jubilee Gold. This innovative 18 ct gold alloy, developed in-house, features a blend of yellow, grey, and pink tones, setting it apart from the traditional yellow, white, and Everose gold options offered by Rolex. This particular reference smartly pairs the new alloy with a light green aventurine dial and a fluted bezel, creating an eye-catching connection between the case, bracelet, and dial with their contrasting materials.

The watch sports a 40 mm Oyster case made solely from the 18 ct Jubilee Gold, adhering to the classic Day-Date design elements such as a monobloc middle, a screw-down case back, and a Twinlock screw-down crown. The distinctive fluted bezel remains a hallmark of the model, and the sapphire crystal, fitted with a Cyclops lens for the date, features an anti-reflective coating, providing a water resistance of up to 100 metres. The polished surfaces of the case and bezel highlight the new alloy, making it a central feature of the watch.

The aventurine dial is another standout aspect, fabricated from natural quartz stone and adorned with ten baguette-cut diamonds marking the hours, which provides a textured, reflective quality unlike the more common lacquered or sunray dials in Rolex's collection. The hands are crafted from 18 ct Jubilee Gold, following the traditional Day-Date layout with the day display at 12 o'clock and the date at 3 o'clock. Powered by the Rolex calibre 3255, a self-winding movement tailored for the Day-Date that supports rapid setting of the day and date alongside a stop-seconds function, it operates at 28,800 vibrations per hour and boasts a power reserve of around 70 hours. The watch is completed with a President bracelet made of 18 ct Jubilee Gold, known for its polished center links, satin-finished outer links, and ceramic inserts that enhance durability and comfort on the wrist, with a concealed Crownclasp that maintains the bracelet's sleek design. Overall, the Day-Date 40 228235JG-0001 is distinguished by its innovative alloy and how seamlessly it integrates into Rolex's timeless watch framework.
