The 26400SO.OO.A002CA reference positions this replica Royal-Oak-Offshore 44mm as a chronograph in steel and ceramic, making it one of the larger and more complex watches in the Offshore catalog. At 44mm the case exceeds the standard 42mm Offshore diver by enough to create a noticeably different wrist experience. Audemars Piguet uses the “SO” designation to indicate steel and ceramic construction, combining the structural strength of stainless steel with the scratch resistance and visual depth of black ceramic elements.

Technical Overview

• Case diameter: 44mm
• Case material: stainless steel and black ceramic
• Dial: black with chronograph subdials
• Bezel: ceramic octagonal with hexagonal screws
• Crystal: sapphire
• Strap: black rubber
• Movement: automatic chronograph
• Functions: hours, minutes, chronograph, date

The mixed-material approach serves both functional and aesthetic purposes. Ceramic bezel and pusher guards resist surface damage during active use, while the steel case back and mid-case provide the structural rigidity that a chronograph movement requires.

Inside the Movement

The chronograph complication adds elapsed-time measurement with subdials arranged in AP’s standard Offshore layout. Pushers at 2 and 4 o’clock control start-stop and reset functions, protected by the angular guards that define the Offshore chronograph profile. The 44mm diameter provides enough real estate for legible subdials without cramping the dial design. At this size, the watch commands significant wrist presence. Compare the 44mm chronograph platform against the 44mm Forest Green diver to see how the same case size handles different complications. Both are available on the Offshore collection page.

What Sets It Apart

The 44mm Offshore chronograph is the largest regular-production watch in the Offshore range. It appeals to buyers who want maximum impact and functional complexity in their sport watch. The steel-and-ceramic construction splits the difference between an all-steel chronograph and a full-ceramic piece, offering weight reduction in the bezel area while maintaining steel in the structural zones. On wrist, the 44mm case extends beyond the lug line on smaller wrists, so this is a reference best suited for wrist circumferences above 18cm. For anyone who wants the full Offshore chronograph experience at maximum scale, this replica Royal-Oak-Offshore 44mm is the reference that delivers it.
