The 2024 Audemars Piguet Royal Oak Concept Split-Seconds Chronograph GMT Large Date in Chroma Forged Technology carbon is reference 26650FO.OO.D353CA.01. Its standout change is a black-and-blue forged-carbon case with luminous blue pigment; inside is automatic Calibre 4407, combining flyback and split-seconds chronograph functions with a second-time-zone display and large date.
Which Royal Oak Concept is this?
The release covered here is the 43 mm reference 26650FO.OO.D353CA.01. Audemars Piguet’s collection search also lists a separate carbon reference, 26650FA.OO.D002CA.01, under the same model family. The references should not be treated as interchangeable: the available listings do not establish a complete side-by-side specification comparison. Audemars Piguet’s Royal Oak Concept collection provides the catalog reference evidence.
The 26650FO is an update to the Royal Oak Concept Split-Seconds Chronograph GMT Large Date platform introduced in 2023. Reports published by GMT India on September 23, 2024, and webChronos on October 14, 2024, identify the vivid CFT case as the defining feature of this variant. GMT India’s release report and webChronos’s coverage describe the launch.
What Chroma Forged Technology changes
In CFT, colour is applied directly to carbon fibres rather than relying on coloured resin, allowing blue and luminous pigment to appear within the forged-carbon case middle. GMT India reports that AP’s process involves dyeing chopped fibres, arranging them by hand in a mould, layering and resin-finishing them, and pressure-curing the material. The resulting block is then machined for six to eight hours. The same report attributes five years of research and development and a patent to AP; these are reported manufacturer process claims, not independently verified comparative findings.

The case is described as black-and-blue CFT carbon with luminous blue pigment. Black ceramic is used for the bezel, crown, pushers and caseback, while the push-piece guards are titanium. The openworked dial uses blue accents, with luminous hands and markers. AP’s video description presents the material as combining lightness with resistance to shocks, heat and humidity; that is a brand claim rather than a published independent test result. Audemars Piguet’s CFT video description outlines the brand’s material positioning.
What the complications do
- Flyback chronograph: lets the wearer reset and restart the chronograph in one action, useful for timing successive intervals without first stopping and resetting in separate operations.
- Split-seconds chronograph: a second chronograph hand can be stopped to record an intermediate time while the main hand continues; it can then catch up with the running hand.
- GMT / second time zone: provides a way to track a second time zone alongside local time.
- Large date: the date display is positioned at 12 o’clock.
