Audemars Piguet Royal Oak Offshore Chronograph 2026 – Ceramic and Titanium with Calibre 4401
Two New Offshore Chronographs in Ceramic and Titanium
Audemars Piguet has presented two new Royal Oak Offshore Selfwinding Chronograph models for 2026, both built around ceramic, titanium, and strong colour contrasts. According to Monochrome Watches, since its debut in 1993, the Royal Oak Offshore has served as the brand's most expressive, aggressive, and experimental platform — bigger, bolder, and much more muscular than the original Royal Oak.
The 2021 redesign marked an important milestone for the collection, refining ergonomics, reworking the 43mm case, and introducing the in-house integrated flyback chronograph calibre 4401. For 2026, AP presents two visually distinct models that retain the current-generation construction while pushing into new material and colour territory.
"Bleu Nuit, Nuage 50" Ceramic Edition
The first model features a full case executed in "Bleu Nuit, Nuage 50" ceramic, the deep, almost inky blue shade introduced for Audemars Piguet's 150th anniversary. The ceramic case is subtly contrasted with titanium elements, including the caseback frame and push-piece guards. As always with AP, the ceramic is finished to the same standards as precious metal, with alternating satin-brushed surfaces and polished bevels.
The dial features a beige Méga Tapisserie base with blue subdials matching the case colour. Rhodium-coated pink gold hour markers and white gold hands are filled with luminescent material. A beige inner bezel with the tachymeter scale frames the display, and the date window is at 4:30. The watch is worn on a dark blue textured calfskin strap with an interchangeable system.
Titanium and Black Ceramic Edition
The second reference takes a more aggressive approach, combining a lightweight titanium case with black ceramic components. The octagonal bezel, crown, and pushers are all made of black ceramic, creating a sharp contrast against the brushed titanium mid-case. This model introduces a new smoked green PVD Méga Tapisserie dial with black subdials featuring beige outer tracks.
Blackened white gold hands and hour markers, filled with beige lume, add to the utilitarian character. A grey-green rubber strap with an interchangeable system completes the package.
Calibre 4401: The Mechanical Constant
Both watches are powered by Audemars Piguet's calibre 4401, visible through the sapphire caseback. This modern integrated flyback chronograph features a column wheel and vertical clutch, enabling smooth chronograph engagement and instant flyback. Beating at 28,800 vibrations/hour and offering a 70-hour power reserve, the movement is finished to haute horlogerie standards with Côtes de Genève, polished bevels, and a blackened oscillating weight.

Frequently Asked Questions
What is a flyback chronograph?
A flyback chronograph allows the user to reset and instantly restart the chronograph with a single push of the reset button, without first stopping it. This is particularly useful for timing consecutive events. The calibre 4401 achieves this through its column wheel and vertical clutch mechanism.
Why does the ceramic version cost more?
The "Bleu Nuit, Nuage 50" ceramic version is priced at CHF 50,900 compared to CHF 36,800 for the titanium and black ceramic model. The premium reflects the complexity of manufacturing and finishing high-tech ceramic to the same standards as precious metals, as well as the heritage significance of the "Bleu Nuit" colour.
Are the straps interchangeable between models?
Yes, both models feature AP's interchangeable strap system. However, the specific straps are designed for each model's aesthetic — the ceramic version pairs with a dark blue textured calfskin strap, while the titanium version uses a grey-green rubber strap.
