Audemars Piguet - Royal Oak 15407ST 41mm Openworked SS/SS Skeleton Dial THBF V3 SH3132 Free Sprung

THB Factory presents the Audemars Piguet Royal Oak Skeleton 15407 with a newly customized integrated movement.

The standout feature of the 15407 is undoubtedly the eye-catching balance wheel and balance bridge at the 8 o'clock position. THB’s custom-made balance wheel, with its rich golden luster, offers endless appeal. As the balance wheel spins, each gear moves in a harmonious sequence, showcasing the beauty of mechanical craftsmanship. A closer look reveals the intricate polishing of each gear and bridge, a testament to the exclusive artistry of high-end watchmaking.

Designed by the legendary Gérald Genta, the Royal Oak boasts not only its iconic integrated bracelet but also exceptional comfort, thanks in part to the precision in case thickness. The case, locked securely with eight hexagonal screws, minimizes the thickness of the case back. The thickness of the three-hand movement is controlled at just 10.1mm—remarkable, especially with a transparent case back.

THB V3 15407 — Quick Reddit Consensus

• Free‑Sprung Movement: V3’s main mechanical change is the free‑sprung balance upgrade.
• Single vs Double Balance: THB (and Octa) V3 variants typically have a single functional balance, not the dual‑balance of some DDF models.
• Balance Finishes Issues: Some users note recurring finish/color inconsistencies on the balance bridge.

• Bezel/Case Proportions (Bezel Gap): The most frequent criticism is the bezel being proportionally small, producing a visible gap.
• Gap Not Universally Fixed: Some releases may appear corrected in marketing images, but users warn that standard models still show the gap.
• Community Desire for Case Fix: Many want the factory to correct the case rather than focus only on movement changes.

• DDF vs THB V3: DDF is recommended by some for overall package, but DDF copies may have decorative or non‑functional secondary wheels.
• For Enthusiasts Who Prioritize Movement: If free‑sprung regulation is your priority, THB V3 delivers that mechanical upgrade.
