The iconic everyday luxury sports watch that started the modern Royal Oak legacy, with perfect finishing and true factory dimensions.

The heart of this 15400 is the APSF custom-built 3120 automatic movement. Built around the genuine cal.3120 architecture, not a cheap modified generic movement. This allows for a slim, balanced profile and authentic operation that matches the original in every way.

✅ Power Reserve: Approx 65 hours (Real world tested).

✅ Functionality: True time, date, small seconds at 9 o’clock with correct layout.

✅ Rotor Spec: Signature skeletonized “Audemars Piguet” oscillating weight for a classic, authentic look.

Solid 316L Stainless Steel

Full 316L stainless steel construction with factory-perfect brushing and polishing. The integrated bracelet links have tight, even gaps and smooth articulation, feeling identical to the genuine on the wrist.

Bleu Nuit (Blue) Grande Tapisserie

The legendary “Grande Tapisserie” pattern with correct depth and light reflection. Applied white gold hour markers and hands with blue luminescence. Date window at 3 o’clock with genuine-matching font and positioning.

Iconic Octagon

Vertical brushing on the surface with sharp, high-polish beveled edges. The 8 signature hexagonal stainless steel screws are perfectly recessed and aligned to factory spec.

9.8mm Thickness

This is the key spec. While many replicas appear thick and bulky, APSF delivers the true 9.8mm ultra-slim profile. It sits low and elegant on the wrist and slides easily under a shirt cuff.

🏆 Why We Chose APSF for this Model?

Many clients ask: “Why APSF over other versions?”

Here is the honest truth: While other factories focus only on dial color, APSF wins in case finishing, bracelet comfort, and most importantly, the true 9.8mm thickness. For the 15400, wrist feel and overall proportions are what make it genuine-looking. APSF delivers the most complete, faithful replication available.

Full Disclosure: Solid stainless steel construction offers great daily durability. The rotor on the clone 3120 may be slightly audible in a completely silent room, which is normal for this movement structure.
