The Audemars Piguet Royal Oak Selfwinding Chronograph 26240ST.OO.1320ST.07 brings together the defining elements of the modern Royal Oak Chronograph: a Silver-toned 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 version selected by D.Time focuses equally on case proportions, dial and bracelet finishing, and the mechanical experience of a true integrated chronograph architecture.
The Silver-toned Grande Tapisserie dial is not a flat white surface. Its geometric texture creates strong depth while the silver tone shifts naturally from bright metallic silver to softer grey depending on the light.
Three matching chronograph subdials maintain a cohesive appearance, while applied baton indexes, central hands and the date at 4:30 preserve the balanced 26240ST layout.
D.Time evaluates silver tone, Grande Tapisserie definition, index alignment, hand positioning, subdial execution and date centering on each individual timepiece.
The three chronograph counters are an essential part of the 26240ST architecture. Their size, spacing and alignment directly influence the visual precision of the dial.
The Silver-toned configuration makes these details particularly easy to evaluate, allowing finishing quality and alignment to remain fully visible rather than being concealed by a darker dial.
The 41 mm case with a 12.4 mm profile maintains the broad, integrated and relatively slim architecture that defines the Royal Oak Chronograph despite housing a fully functional automatic Flyback movement.
This profile allows the bezel, mid-case and bracelet to flow naturally together, preserving the characteristic Royal Oak side view.
The case and bracelet combine directional brushing with sharp polished bevels, producing the contrast that defines the Royal Oak under changing light.
D.Time evaluates the eight bezel screws, brushing consistency, polished transitions, bevel definition and seamless integration between the case and bracelet.
Inside is the SA4401 Super Clone Free-Sprung, an integrated automatic chronograph operating at 28,800 vph / 4 Hz with up to 70 hours of power reserve.
The chronograph is built directly into the movement architecture rather than added as a separate module, creating a cleaner mechanical layout that closely follows the design logic of Calibre 4401.
The Flyback Chronograph is fully functional, allowing the running chronograph to be reset and immediately restarted with a single press rather than requiring a conventional stop-reset-start sequence.
This gives the 26240ST genuine mechanical functionality beyond visual replication and recreates one of the defining features of Calibre 4401.
The sapphire exhibition caseback reveals the rotor, bridges, balance assembly and integrated chronograph architecture. The Free-Sprung configuration gives the balance area a cleaner and more refined mechanical presentation.
D.Time evaluates movement cleanliness, rotor operation, start/stop functionality, Flyback operation and precise zero-reset before delivery.
The integrated bracelet flows directly from the case and combines brushed surfaces with polished bevels, extending the finishing language of the Royal Oak continuously around the wrist.
D.Time evaluates link articulation, case-to-bracelet fit, surface consistency and AP double-folding clasp operation.
This version brings together the defining qualities of the 26240ST: a sharply executed Silver-toned Grande Tapisserie dial, 41 mm × 12.4 mm case, integrated bracelet and the SA4401 Super Clone Free-Sprung with a fully functional Flyback Chronograph.
The Silver-toned dial places finishing quality fully on display, while the SA4401 completes the mechanical experience with integrated chronograph architecture, functional Flyback, 4 Hz operation and up to 70 hours of power reserve.
D.Time individually evaluates the Grande Tapisserie dial, three subdials, indexes, date display, eight bezel screws, polished bevels, case and bracelet finishing, sapphire caseback, rotor and SA4401 Super Clone movement operation. The version supplied by D.Time features 5 ATM water resistance.
Each Timepiece is individually inspected by D.Time before delivery, with photos and videos of The Exact Timepiece You Will Receive.
