41mm Black Grande Tapisserie Edition

Name: Audemars Piguet Super Clone Royal Oak Black Dial 26240 Chronograph 41mm
SKU: 4863
Availability: InStock

A milestone in chronograph engineering, eliminating modular thickness to achieve an authentic 12.1mm case profile. Powered by an integrated Calibre 4401 clone movement, this 41mm DDF reference combines deep black tapisserie artistry with precision-brushed steel articulation.

I / Chronometric Calibre Performance

The integrated Calibre 4401 clone movement acts as the mechanical heart of this reference, abandoning compromised Valjoux 7750 transfer-gear setups. DDF engineered this integrated chronograph layout to align sub-dial registers naturally: running seconds at 6 o’clock, chronograph minutes at 9 o’clock, and chronograph hours at 3 o’clock. Movement bridges feature perlage and Geneva wave finishing, storing a stable 36-hour power reserve.

▹ Integrated Calibre 4401 Chronograph Engine (True Sub-Dial Spacing)
▹ Fully Functional Chronograph with Running Seconds at 6 O’Clock
▹ Perlage & Côtes de Genève Decorated Bridges Viewable via Sapphire

II / Material Execution & Casing Parity

Cold-forged 316L stainless steel constructs the 41mm case shell to a verified 12.1mm profile thickness and 170.7g mass. The black Grande Tapisserie dial showcases deep guilloché squares with concentric snailing on the sub-dials. Eight white gold-plated hexagonal screws sit flush inside the octagonal bezel, while the integrated steel bracelet delivers fluid link flexibility and AP double-deployant security.

▹ CNC-Milled 316L Steel Case (12.1mm Profile | 170.7g Total Mass)
▹ Black Grande Tapisserie Dial with Concentric Snailing Sub-Dials
▹ Integrated Steel Bracelet with Alternating Brushed & Polished Links

Factory Curation Analysis — DDF Benchmarks

Collectors select DDF as the primary choice for the Royal Oak Chronograph 26240 reference due to superior movement architecture and case slimness. Older market builds using modified Valjoux movements suffered from inflated case profiles over 14mm thick and compromised sub-dial spacing. DDF’s dedicated 4401 clone architecture achieves the verified 12.1mm profile while maintaining fluid link articulation across the integrated bracelet.

Atelier Technical Disclosure: Under high-magnification loupe inspection, the date wheel typography can present a slightly thicker ink weight compared to genuine AP printing.

Collector FAQ & Technical Insights

Does the chronograph function correctly on this DDF release?
+

Yes. The Calibre 4401 features a fully functional integrated chronograph. The sub-dials operate with running seconds at 6 o’clock, chronograph minutes at 9 o’clock, and chronograph hours at 3 o’clock.

How does the 12.1mm thickness compare to older replica chronographs?
+

Older replicas using modified Valjoux 7750 movements often exceeded 14mm in thickness. DDF’s dedicated 4401 clone movement allows this model to achieve the verified 12.1mm profile, matching genuine proportions closely.

Are the integrated bracelet links interchangeable with genuine AP links?
+

While DDF bracelet dimensions and alternating finishes closely match genuine specs visually, internal pin and sleeve tolerances differ microscopically. Mixing replica and genuine links is not recommended.

What is the main known detail on this DDF 26240 release?
+

Under macro loupe inspection, the date wheel typography can appear marginally thicker than genuine AP font printing, a common characteristic among current clone date discs.
