APSF Edition — Integrated Stainless Steel Bracelet
The APSF Audemars Piguet Royal Oak 15400ST has established itself as a definitive benchmark within the replica community, primarily due to its true 1:1 case construction and the elimination of the Miyota 9015 base. By utilizing a fully integrated clone movement, APSF achieves the exact 9.8mm case thickness and correct crown height of the genuine reference. This architectural precision extends to the movable link design connecting the case head to the bracelet, mirroring OEM assembly methods and allowing for genuine part interchangeability.
At the core of this reference is the custom clone Caliber 3120 automatic movement. Unlike earlier iterations that relied on decorated plates over standard ebauches, this caliber features a seamless integrated construction that eliminates the noisy unidirectional rotor spin common to Miyota-based replicas. It operates at a smooth 21,600 vph (3Hz), matching the genuine beat rate, and delivers a power reserve of approximately 36 hours. The engraved 22k gold-plated rotor features accurate AP crests, while the movement bridges showcase appropriate perlage and côtes de Genève finishing.
The 41mm case is milled from high-grade stainless steel, exhibiting the signature Royal Oak alternating brushed and polished finishing. The grey Grande Tapisserie dial is accurately stamped, capturing the intricate square texture and concentric snailed pattern of the original ruthenium dial. The bezel features the iconic octagonal profile with eight polished, white gold-plated hexagonal screws, sitting flush against the brushed surface, protected by a glareproofed sapphire crystal.
