Audemars Piguet Royal Oak Chronograph 26240ST Black — Distinctive 50th Anniversary Character
The Audemars Piguet Royal Oak Selfwinding Chronograph 26240ST.OO.1320ST.02 belongs to the 50th Anniversary generation, combining a Black Grande Tapisserie dial, 41 mm × 12.4 mm stainless-steel case, integrated bracelet, sapphire exhibition caseback and SA4401 Super Clone Free-Sprung with a fully functional Flyback Chronograph.
The black dial creates strong contrast against the polished indexes, hands, bezel screws and bevels, emphasizing the geometric architecture of the Royal Oak.
Black Grande Tapisserie — Depth through Texture
The Black Grande Tapisserie dial creates depth through its geometric texture rather than relying on complex color effects. Changing light produces subtle highlights and shadows across the tapisserie surface.
Three black chronograph subdials preserve a cohesive monochromatic presentation, while polished indexes and hands create strong visual contrast.
D.Time evaluates Grande Tapisserie definition, subdial layout, index alignment, hand positioning and date centering at 4:30.
Three Chronograph Subdials — Precision in Every Position
The three chronograph counters play a major role in the visual accuracy of the 26240ST. Their proportions, spacing, concentric finishing and hand positioning must remain balanced across the dial.
The Black configuration makes metallic details and printing especially clear, allowing D.Time to evaluate alignment and finishing directly.
41 mm × 12.4 mm Case — Balanced Royal Oak Chronograph Proportions
The 41 mm case with a 12.4 mm profile preserves the broad yet relatively slim architecture of the Royal Oak despite housing a fully integrated automatic chronograph movement.
The octagonal bezel, eight exposed screws and integrated bracelet create the continuous geometry that defines the model.
Brushed Surfaces & Polished Bevels
The case and bracelet combine directional brushing with polished bevels, creating sharp contrast under changing light. The dark dial makes these steel surfaces especially prominent.
D.Time evaluates bezel screws, brushing direction, polished transitions and seamless case-to-bracelet integration.
SA4401 Super Clone Free-Sprung — Integrated Chronograph Architecture
The SA4401 Super Clone Free-Sprung operates at 28,800 vph / 4 Hz, provides up to 70 hours of power reserve and integrates the full Flyback Chronograph directly into the movement architecture.
This construction closely follows the mechanical logic of Calibre 4401 and gives the movement particular visual value through the sapphire exhibition caseback.
Fully Functional Flyback Chronograph
The Flyback Chronograph is fully functional, allowing the running chronograph to reset and immediately begin a new timing sequence with a single press.
D.Time checks start, stop, Flyback operation and precise zero-reset of the chronograph hands before delivery.
50th Anniversary Rotor — Essential Reference .02 Identity
Reference 26240ST.OO.1320ST.02 belongs to the 50th Anniversary generation, making the commemorative rotor an important part of its correct rear-side presentation.
Through the sapphire exhibition caseback, the rotor, bridges, balance assembly and chronograph architecture remain fully visible. D.Time verifies the correct 50th Anniversary configuration together with movement finishing and operation.
Integrated Stainless-Steel Bracelet — Seamless Royal Oak Finishing
The integrated bracelet continues the case finishing with brushed surfaces and polished bevels, creating a seamless transition from the case around the wrist.
D.Time evaluates link articulation, case-to-bracelet fit, finishing consistency and AP double-folding clasp operation.
