Audemars Piguet Royal Oak Offshore Chronograph 26400IO
Original price was: $1,699.00.$1,299.00Current price is: $1,299.00.
This 44mm Royal Oak Offshore Chronograph 26400IO is built in 904L heavyweight steel with a black Korean ceramic bezel, slate grey Méga Tapisserie dial, and active rubber strap. Its integrated Caliber 3126 super clone delivers the correct chronograph layout with sub-dials at 6, 9, and 12, a large date display, and approximately 36 hours of power reserve.
44mm Offshore Chronograph in 904L Heavyweight Steel
This Audemars Piguet Royal Oak Offshore Chronograph 26400IO is configured as a large-format 44mm sports chronograph with a substantial 904L heavyweight steel case. The build is centered on presence and mechanical complexity, with a total weight of 196g and alternating brushed and polished finishing across the case. This version uses steel rather than titanium, giving the watch a distinctly weighty character on the wrist while keeping the reference focused on the bold Offshore format.
The case measures 44mm in diameter with a stated thickness of 14.4mm. Its proportions are paired with an active rubber strap and steel pin buckle, giving the watch a purposeful configuration that matches the chronograph architecture and broad case footprint.
Black Korean Ceramic Bezel and Slate Grey Méga Tapisserie Dial
One of the defining details of this 26400IO is its black Korean ceramic bezel. The top surface is brushed, with polished flanks adding contrast around the case. The ceramic construction is chosen for scratch resistance and frames the dial with a crisp technical look that suits the Offshore chronograph layout.
The dial is finished in slate grey with the Méga Tapisserie pattern. It is paired with black sub-dials and red chronograph accents, creating the exact visual contrast that gives this configuration its identity. The chronograph display is laid out with sub-dials at 6, 9, and 12 o’clock, and the watch also includes a correct large date display. The date wheel uses the large font specific to the 3126-style configuration, which is part of what makes this version stand out to buyers who pay attention to dial execution and movement-matched details.
Integrated Caliber 3126 Super Clone
At the center of this watch is the integrated Caliber 3126 super clone. This is not based on a modified 7750 layout, and that difference matters in the way the dial is executed. The movement delivers the correct sub-dial spacing and date window depth for this Offshore chronograph format, preserving the intended layout of the 26400IO.
The movement includes a decorated free-sprung balance wheel and upgraded jewel bearings. It is also described with bidirectional winding and approximately 36 hours of power reserve. The chronograph is fully functional, including a 12-hour chronograph display and running seconds. Pusher resistance is noted as authentic in feel, adding to the mechanical character expected from a watch in this category.
Through the exhibition caseback, the decorated balance architecture is visible, reinforcing the movement-focused appeal of this APSF edition. The mechanism is also noted for resolving the seconds-hand stutter associated with earlier market versions, giving this build a more stable chronograph presentation.
Active Rubber Strap, Sapphire Crystal, and Large-Wrist Presence
The watch is fitted on an active rubber strap that sits flush to the case and closes with a heavyweight steel pin buckle. That strap choice keeps the overall specification in line with the sporty Offshore profile while balancing the mass of the steel case. The crystal is double-sided scratch-proof sapphire with AR coating, a practical pairing for a dial with layered texture and multiple indications.
This edition is built for buyers who want the 44mm Offshore chronograph format with the integrated 3126 architecture, ceramic bezel, and heavyweight steel construction. The large case size and 196g overall weight give it a substantial wrist presence, especially for those shopping specifically for a broad, mechanical chronograph with a more solid feel.
