Under a new “Exceptional Creations” umbrella that highlights innovative alloys and material pairings, Rolex has introduced a new Rolex Daytona 126502 at Watches and Wonders Geneva 2026.
The 126502 comes in a Rolesium execution, combining Rolex Oystersteel with platinum, complemented by an anthracite Cerachrom bezel. In practical terms, this translates to a mix of steel and platinum across the case, paired with a steel bracelet and a grey ceramic bezel insert.
It is further elevated by a crisp enamel dial and a sapphire caseback, offering a more open view of the movement within.
Those familiar with Rolex terminology will know that Rolesium refers to a combination of steel and platinum within a single watch. On the Rolex Daytona 126502, the middle case and Oyster bracelet are made of Rolex Oystersteel, forming the structural foundation of the watch.
Platinum is used more selectively, appearing on details such as the caseback ring and the slim ring encircling the bezel. As with other Daytona models, the Oyster case measures 40mm in diameter and offers water resistance to 100 metres.
The anthracite Cerachrom bezel insert introduces a new metallic-toned finish, achieved through a ceramic formulation enhanced with tungsten carbide. Visually, it marks a subtle but notable shift, giving the traditionally matte ceramic surface a more reflective, almost metallic sheen.
Rolex has also revised the tachymeter scale, returning to a more vintage-inspired layout with horizontally aligned numerals reminiscent of early Rolex Daytona models from the 1960s. The numerals themselves appear slightly suspended, rendered in a modern typeface and filled with platinum via PVD for added depth and contrast.
The dial takes a distinctly different direction. In this execution, Rolex opts for a white enamel surface created using the grand feu technique, where the material is fired at temperatures exceeding 800°C.
Rather than being applied directly onto a metal base, the enamel is first laid onto ceramic plates, which are then mounted onto a brass base after firing. This results in a bright, glossy white dial with exceptional depth and uniformity—qualities that are difficult to replicate with lacquer.
The subdials are produced using the same process, ensuring visual consistency across the entire dial while providing a subtle contrast against the darker bezel.
Turning the watch over reveals a sapphire crystal caseback—an increasingly familiar feature on select Rolex Daytona models, including the Le Mans editions and the “Platona.” The display offers a clear view of the Calibre 4131 inside, continuing Rolex’s modern chronograph architecture with a column wheel and vertical clutch system.
The movement operates at 4 Hz and provides an approximate 72-hour power reserve. It also integrates the Chronergy escapement, Parachrom hairspring, and Paraflex shock absorbers for improved efficiency and durability. Finishing details include Rolex Côtes de Genève across the bridges and a skeletonized oscillating weight crafted in yellow gold.
As with many Rolex Daytona models, the 126502 is fitted on a classic Oyster bracelet in Rolex Oystersteel, complete with the Oysterlock safety clasp and Easylink extension system for quick, on-the-fly micro-adjustments.
In terms of genuine innovation, it is fair to ask what is truly “exceptional” here. The enamel dial is undeniably a refined highlight, and the metallic-effect Cerachrom bezel will be interesting to assess in person. However, the functional impact of the platinum elements on the caseback and bezel ring remains less clear, even if they allow Rolex to frame this as the first Daytona combining steel and platinum in a Rolesium execution.
