APSF Edition — Premium Rubber Strap
The APSF edition of the Royal Oak Offshore Chronograph 26401RO represents a significant structural shift in heavy-case replica manufacturing. Historically, Offshore replicas relied on modified 7750 calibers with transfer modules, resulting in the infamous sunken date wheel and incorrect sub-dial spacing. APSF resolves this by utilizing a true 1:1 clone architecture of the AP Caliber 3126, aligning the sub-dials precisely to genuine specifications while maintaining the correct 15.6mm case thickness.
At the core of this reference is the custom Caliber 3126 automatic chronograph movement. By abandoning the modular approach, the date disc sits flush against the dial surface, eliminating the shadow effect seen on earlier iterations. The movement features a fully functional chronograph with hours, minutes, and sweep seconds, delivering a power reserve of approximately 36 hours.
The 44mm case is constructed from stainless steel with a heavy 18K rose gold plating, bringing the total weight to a substantial 202.1 grams. The alternating brushed and polished finishing on the case flanks pairs with a precisely machined black ceramic bezel. The black mega tapisserie dial features correct text depth and applied rose gold-toned markers, shielded by a glareproofed scratch-resistant sapphire crystal.
