Description
APSF Audemars Piguet Royal Oak Selfwinding 34mm 77350ST
The APSF 77350ST establishes a stringent horological benchmark by achieving the critical 8.8mm thickness and 115.7g weight parameters.
Powered by Cal.3120 Clone Automatic
The Cal.3120 clone automatic movement provides the necessary structural thinness to achieve the 8.8mm case profile. It features custom rotor engravings and bridge decorations that mimic the genuine architecture. Operating at a stable frequency, it ensures a smooth sweep for the center seconds hand while maintaining reliable torque.
Typically regulated to 卤10��15 seconds per day, which is standard for this specific clone architecture. Professional regulation can often yield tighter tolerances.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Hours, minutes, center seconds, and rapid-advance date display
- �� Winding Direction: Unidirectional (rotor winds in one direction)
Technical Specifications
Constructed to exact 34mm diameter and 8.8mm thickness specifications. The case exhibits a highly accurate ratio of polished chamfers to brushed flat surfaces.
The dial features crisp printing and applied indices, with a subtle #006039 hue visible under direct lighting, accurately replicating the genuine depth.
Signature octagonal geometry secured by eight polished hexagonal screws, sitting perfectly flush with the brushed bezel surface.
Features tight link tolerances and precise edge finishing, secured by a reliable AP folding double-deployant clasp.
Why APSF for This Reference?
Many collectors ask: ��Why not ZF?��
While ZF produces excellent larger Royal Oak variants, APSF has mastered the integrated bracelet tolerances and precise 8.8mm thickness specifically for the 34mm 77350ST. The alternating brushed and polished finishing on the APSF bracelet links exhibits superior light play compared to rival batches.
Full Disclosure: The underlying movement architecture can exhibit slight rotor noise during vigorous wrist movement, a common trait in thin automatic clone calibers.

Collector Q&A
Q: Does the APSF 77350ST have the correct case thickness?
A: Yes, the APSF version measures exactly 8.8mm in thickness, matching the genuine profile. This is achieved through the use of a streamlined Cal.3120 clone movement.
Q: How does the weight of this replica compare to the genuine?
A: The APSF 34mm Royal Oak weighs precisely 115.7g, providing a highly accurate tactile feel and heft on the wrist compared to its genuine counterpart.
Q: Are the bracelet links interchangeable with genuine links?
A: While the external geometry and finishing closely mimic the genuine integrated bracelet, the internal pin and screw tolerances may vary slightly. We do not recommend attempting to mix APSF links with genuine AP links.
Q: Is rotor noise noticeable on this Cal.3120 clone?
A: As with many ultra-thin automatic clone movements, there can be mild unidirectional rotor noise in a quiet room. This is a known characteristic of the base caliber used to achieve the 8.8mm case profile.
