The Daytona Evolves: Exploring The Rolex Rolesium Ref. 126502
For decades, the Rolex Cosmograph Daytona has stood as one of the most recognizable and sought-after chronographs in watchmaking. Introduced in 1963, it has evolved carefully over time—often within strict aesthetic boundaries. With the new Rolesium reference 126502, Rolex expands those boundaries, introducing a fresh material combination and several notable technical and design updates.
A Familiar Case, Subtly Refined
The foundation of the new Rolesium Daytona remains consistent with the latest generation introduced in 2023. The Oystersteel case measures 40 mm in diameter and approximately 11.90 mm in thickness, offering balanced proportions and improved symmetry thanks to refined lugs and a more cohesive profile.

In terms of functionality, the watch retains all the core attributes expected from the Daytona. It is water-resistant to 100 meters and fitted with a screw-down crown and chronograph pushers, ensuring durability and reliability in daily use. The sapphire crystal, enhanced with anti-reflective coating, further improves legibility while maintaining robustness.
Rolesium: Steel Meets Platinum
What sets the reference 126502 apart is its Rolesium construction—a combination of Oystersteel and platinum. This pairing is most evident in the bezel, which is framed by a platinum ring, as well as in the caseback, also crafted from platinum. Notably, this marks the first time a predominantly steel Daytona incorporates such a feature, adding both visual distinction and material prestige without compromising the model’s sporty DNA.
A New Ceramic Bezel with Vintage Influence
The Cerachrom bezel insert introduces both material and design evolution. Crafted from a zirconia-based ceramic enriched with tungsten carbide, it offers enhanced resistance to wear while presenting a distinctive anthracite tone.

Equally important is the redesign of the tachymeter scale. Instead of the more contemporary layout seen on recent models, this version adopts a vintage-inspired aesthetic reminiscent of Daytona references from the 1960s. The numerals are horizontally engraved, accompanied by intermediate baton markers and small dots that enhance readability. The scale progression itself has also been refined, now displaying a more gradual sequence that includes 160, 150, and 140 markings, reinforcing its retro appeal.
A First: White Enamel Dial Without Contrast
One of the most striking elements of this reference is its dial. Departing from the traditional “panda” or reverse-panda configurations, the watch features a fully white enamel dial with matching sub-counters—an unprecedented look for a standard steel Daytona.

This dial is produced using the grand feu enamelling technique, an intricate process that involves coating ceramic plates which are then fired at high temperatures. After vitrification, these elements are mounted onto a brass base, resulting in a smooth, uniform surface with remarkable depth and durability. The absence of contrasting sub-dials creates a cleaner, more minimalist aesthetic while maintaining the Daytona’s signature layout.
Calibre 4131 on Display
Inside the watch beats the calibre 4131, Rolex’s latest-generation automatic chronograph movement. While its architecture remains consistent with other current Daytona models, its presentation here is notably different.

For the first time in a steel-based Daytona, the movement is visible through a sapphire caseback. This allows a clear view of its refined construction, including the column wheel and vertical clutch system that ensures precise chronograph operation. The movement also incorporates the Chronergy escapement, designed to improve efficiency and resistance to magnetic interference, along with a blue Parachrom hairspring for enhanced stability.
Operating at a frequency of 4 Hz, the calibre 4131 delivers a power reserve of approximately 72 hours. It is finished with Rolex Geneva-style striping and features a solid gold rotor, underscoring the elevated nature of this particular reference.
Oyster Bracelet and Wearability
The watch is fitted with the classic three-link Oyster bracelet in Oystersteel, combining brushed and polished finishes to create a refined yet sporty appearance. It is secured by an Oysterlock folding clasp, which provides additional safety, and includes the Easylink comfort extension system, allowing the wearer to easily adjust the bracelet length for improved comfort throughout the day.
Availability and Positioning
The Rolex Cosmograph Daytona Rolesium ref. 126502 is part of the brand’s off-catalogue offerings, making it less visible but highly desirable among collectors. It is priced at € 56,160, positioning it between traditional steel models and full precious metal variants.
Final Thoughts
With the Rolesium 126502, Rolex introduces meaningful evolution without straying from the Daytona’s core identity. The combination of platinum elements, a vintage-inspired bezel, and a fully enamel dial marks a rare departure from tradition—a piece that adds depth and variety to one of watchmaking’s most iconic chronographs, and perhaps one of the best-executed contemporary Daytonas.
