Description
APSF Audemars Piguet Royal Oak Offshore Diver 15720ST ��Khaki Green��
The most mechanically accurate iteration of the modern Offshore Diver, distinguished by its plate-free Caliber 4308 architecture and precise case geometry.
Powered by Caliber 4308 Super Clone
The mechanical foundation of this APSF release is the true-clone Caliber 4308. Moving away from the compromised architecture of previous generations, this movement is built entirely to the specifications of the genuine caliber, omitting the need for glued decorative plates. This structural integrity ensures the balance wheel oscillates in the exact correct position at 12 o��clock when viewed from the exhibition caseback. The rotor features refined brushing and precise engravings, while the gear train delivers a stable, authentic tactile response when manipulating the crown for time and date setting.
Regulated by APSF to operate within an expected deviation of 卤10��15 seconds per day. The free-sprung balance design provides reliable daily stability when fully wound.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Hours, minutes, center seconds, date display, and inner rotating diving scale
- �� Winding Direction: Bidirectional automatic winding via central rotor
Technical Specifications
Measuring exactly 42mm in diameter and verified at 14.1mm thick with a total weight of 174.4g. The case exhibits APSF��s signature brushed/polished alternating finishing, matching the sharp, industrial transitions of the genuine Offshore profile.
Executed in a highly accurate khaki green tone. The dial features crisp, deeply stamped tapisserie squares, applied white gold-plated hour markers, and luminescent hands that provide excellent low-light legibility.
Features the iconic octagonal steel outer bezel secured by hexagonal screws, paired with a functional inner rotating dive scale manipulated by the ceramic-clad crown at 10 o��clock.
A durable khaki green rubber strap equipped with APSF��s replicated quick-change system. The mechanism allows for rapid strap swaps while maintaining a tight, secure integrated strap fit against the case.
Why APSF for This Reference?
Many collectors ask: ��Why not ZF?��
While ZF produces excellent steel Royal Oak variants, APSF is the definitive choice for the 15720 due to their proprietary Cal. 4308 movement and superior case finishing. APSF��s dedication to the true-clone architecture eliminates the thickness discrepancies and visual tells associated with decorated base movements. Furthermore, the tolerances on APSF��s quick-release strap mechanism are noticeably tighter, ensuring less endplay where the strap meets the lugs.
Full Disclosure: The inner rotating bezel crown at 10 o��clock exhibits slightly less damping resistance than the genuine article when turning, though it holds its position securely once set.

Collector Q&A
Q: Does the quick-release strap system work identically to the genuine Audemars Piguet mechanism?
A: Yes, the APSF 15720 features a fully functional quick-release mechanism integrated into the case lugs and buckle. This allows for tool-free strap changes that function with the same press-and-release logic as the genuine article, and the lug tolerances are precise enough to accept authentic AP rubber straps.
Q: How accurate is the M茅ga Tapisserie khaki green dial color on the APSF version?
A: The APSF dial achieves a highly accurate khaki green tone. While under direct, harsh sunlight it may appear marginally flatter than the genuine multi-layered lacquer finish, the dimensional depth of the tapisserie squares and the color matching under standard indoor lighting are class-leading.
Q: Is the Caliber 4308 in this model a decorated base movement or a true clone?
A: It is a true clone. Unlike earlier replica generations that utilized a standard base movement with decorative plates glued on top, APSF engineered the 4308 caliber from the ground up. This structural accuracy ensures the balance wheel is correctly positioned and visible through the sapphire caseback without the added thickness of false plates.
Q: What is the main limitation or known quirk of the inner rotating diver bezel?
A: While the inner rotating bezel is fully functional via the 10 o��clock crown, the gearing tolerance is slightly looser than genuine. Collectors often note a minor amount of play or lack of heavy damping before the inner bezel engages, though it holds its desired position securely once set.
