APSF Specialized Master Curation

Audemars Piguet Royal Oak Offshore Diver 15720ST
42mm Khaki Green Méga Tapisserie Edition

Name: Audemars Piguet Super Clone 1:1 Royal Oak Offshore 15720 Green Dial
SKU: 11675
Availability: InStock

The most mechanically accurate iteration of the modern Offshore Diver. Powered by an integrated Caliber 4308 clone movement without decorative cover plates, this 42mm reference combines a functional quick-release strap system with robust industrial case architecture.

I / Chronometric Calibre Performance

The standalone Caliber 4308 Super Clone movement powers this reference with authentic mechanical integrity. Moving away from decorated base plates, APSF built this engine to genuine specifications. The balance wheel oscillates at the correct 12 o’clock position when viewed through the exhibition caseback. The movement drives smooth central sweeping seconds and an instant date change, providing a 36-hour power reserve on the bench.

▹ Integrated Caliber 4308 Standalone Engine (12 O’Clock Balance Wheel Position)
▹ Plate-Free Movement Architecture with Refined Rotor Engravings
▹ Quickset Date Display with Authentic Tactile Crown Response

II / Material Execution & Casing Parity

Cold-forged 316L stainless steel shapes the 42mm case shell to a verified 14.1mm thickness and 174.4g total weight. The khaki green Méga Tapisserie dial presents deep, sharply stamped squares with applied white gold-plated markers. Operated via the ceramic-clad crown at 10 o’clock, the inner dive scale rotates smoothly, while a quick-release khaki green rubber strap completes the build.

▹ Milled 316L Steel Case (14.1mm Profile | 174.4g Mass)
▹ Khaki Green Méga Tapisserie Dial with Swiss Luminous Indices
▹ Functional Quick-Release Rubber Strap System with Pin Buckle

Factory Curation Analysis — APSF Benchmarks

Collectors select APSF as the primary choice for the 15720ST platform due to their proprietary Caliber 4308 engine and superior case integration. Unlike alternative builds using decorated base movements that increase case thickness, APSF achieves correct physical dimensions. Furthermore, the tolerances on APSF’s quick-release strap mechanism remain remarkably tight, minimizing endplay where the rubber joins the lugs.

Atelier Technical Disclosure: The secondary ceramic-clad crown at 10 o’clock controlling the internal dive scale exhibits slightly lighter turning resistance than original models, though it maintains its set position securely once adjusted.

Collector FAQ & Technical Insights

How does the Caliber 4308 clone differ from older movement generations?
+

The Caliber 4308 is an integrated clone built directly to genuine architecture without glued decorative cover plates. This places the balance wheel at the correct 12 o’clock position through the sapphire display back and maintains accurate case thickness.

How does the quick-release strap mechanism perform on this APSF release?
+

APSF replicated the quick-change strap system with tight mechanical tolerances. Pushing the release buttons on the underside of the lugs allows swift strap swaps without tools while locking securely in place.

How accurate is the khaki green dial tone compared to genuine?
+

The APSF khaki green dial captures the correct military-inspired hue. Under direct lighting, the Méga Tapisserie squares reflect light cleanly without showing unwanted olive or grey color shifts.

What is a known operational characteristic of the inner bezel crown?
+

The ceramic-clad crown at 10 o’clock controlling the internal dive scale turns with slightly lighter damping resistance than genuine models, though it holds its alignment position securely once set.
