Description
THB Factory Audemars Piguet Royal Oak 15407 Double Balance Openworked
The V2 update resolves the historical thickness limitations of skeletonized replicas, delivering a true 9.9mm profile with functional front-facing mechanics.
Inside the SA3132 Super Clone
The THB custom SA3132 is a dedicated integrated skeleton caliber based on the 3120 architecture. By abandoning the modular approach of attaching decorative plates to a base movement, THB has achieved a 1:1 split architecture where the front-facing mechanical gears and transmission wheel axles are fully operational. The movement prominently features the signature 8 o��clock golden bridge and balance wheel, providing the necessary visual depth and kinetic activity expected from this openworked reference.
The custom SA3132 caliber is typically regulated to operate within 卤10��15 seconds per day, consistent with high-grade integrated clone movements in this tier.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Hours, minutes, center seconds, openworked dial layout
- �� Winding Direction: Bidirectional
The Technical Breakdown
The 41mm case is CNC machined to an exact 9.9mm thickness. The high-density steel construction yields a substantial 170g weight, featuring precise alternating brushed and polished surfaces.
The openworked dial presents a highly accurate slate grey/charcoal tone. The brand wordmark is applied via heavy ink printing directly onto the inner sapphire crystal, matching genuine specifications.
The signature octagonal bezel exhibits deep vertical brushing on the top surface, contrasted by highly polished, mirror-finished chamfered edges and perfectly aligned hexagonal screws.
The integrated bracelet features tight tolerances between the brushed links and polished mid-link edges, securing to the wrist with a crisp, double-deployant AP folding clasp.
Why THB Factory for This Reference?
A question that comes up often: ��Why not APSF?��
While APSF is the undisputed leader for closed-dial Royal Oak models (like the 15500) due to their excellent 4302 clone, THB is the superior choice for the 15407 openworked reference. THB��s custom SA3132 integrated movement eliminates the need for modular decorative plates, allowing the case to achieve the genuine 9.9mm thickness��a feat older or alternative factory versions fail to accomplish, often sitting at a bloated 10.5mm or thicker. This commitment to dimensional accuracy aligns perfectly with for luxury replicas.
One Caveat: While the 8 o��clock bridge visually replicates the genuine design, the movement utilizes a single balance wheel for timekeeping stability rather than a functional dual-hairspring double balance mechanism.

What Buyers Ask
Q: Does the front gearing on the THB 15407 actually work, or is it decorative?
A: Unlike older versions that used a Miyota 9015 with a static fake top plate, the THB V2 SA3132 movement features functional front-facing gear transmission. The mechanical gears and transmission wheel axles visible on the dial side actively operate.
Q: Is the case thickness exactly 9.9mm like the genuine Audemars Piguet?
A: Yes. By developing an integrated skeleton movement rather than using modular decorative plates, THB successfully reduced the case thickness to exactly 9.9mm, matching the genuine specifications and eliminating the bloated profile of previous replicas.
Q: Are the balance wheels at 8 o��clock fully functional as a double balance?
A: The movement utilizes a reliable single balance wheel for timekeeping stability. While it highly accurately replicates the visual aesthetic of the genuine double balance bridge in rose gold, it does not feature a functional dual-hairspring architecture.
Q: Is the rotor noisy on this skeletonized movement?
A: Because the case lacks a solid dial and utilizes an openworked architecture front and back, rotor sound is slightly more audible than on closed-dial Royal Oak models like the 15500. This is a common characteristic of fully skeletonized replica calibers.
