Audemars Piguet has unveiled its most colourful Royal Oak Offshore season yet, with nine new references across two distinct collections. The 42 mm Selfwinding Chronograph arrives in bold summer hues, powered by the flyback Calibre 4404, while the 37 mm Selfwinding Chronograph makes its debut in titanium and pink gold, carrying the brand’s new Calibre 6401 for the first time.

The Offshore story began in 1993, when designer Emmanuel Gueit drew inspiration from high-performance offshore racing yachts to create something that the watchmaking world had not quite seen before. Oversized proportions, exposed rubber gaskets and an unapologetic attitude to scale earned it the nickname “The Beast” almost immediately. More than thirty years on, that spirit is still very much intact, and this summer’s new releases carry it into a season that suits the collection well.

“First launched in 1993, the Royal Oak Offshore emerged from the creative explosion of the ‘80s. Today, our new 37 mm references are powered by Calibre 6401 and brought to life through vibrant, summer colours that translate this spirit into a contemporary expression of a dynamic and individual style.” Ilaria Resta, Chief Executive Officer, Audemars Piguet

The 42 mm Selfwinding Chronograph

Three new 42 mm references bring pink, turquoise and yellow, and orange to the Royal Oak Offshore Selfwinding Chronograph line, each one built around the signature Méga Tapisserie dial and powered by Calibre 4404, the manufacture’s integrated flyback chronograph movement. The colour arrives via a new printing technique applied to the tachymeter scale and the chronograph counters at 9 and 12 o’clock, giving the dial real depth and making every glance at the watch a satisfying one.

The first model pairs a stainless steel case with a black Méga Tapisserie dial and pink accents running through the seconds hand, counter hands and rubber push-piece at 2 o’clock. Dark and purposeful, it is the most classically Offshore of the three, with the pink used to punctuate rather than dominate. The 15.3 mm case is water-resistant to 100 m and comes with an interchangeable black textured calfskin leather strap with pink stitching.

The titanium reference brings together yellow and turquoise on a dark grey dial, with turquoise luminescent material in the hands that gives the watch a quiet presence in low light. The lightweight construction makes it the most comfortable of the three for a full day’s wear, and the dark grey textured calfskin strap with turquoise stitching ties the palette together neatly.

The third model returns to stainless steel with a silver-toned dial and orange detailing, the orange seconds hand and push-piece making their presence felt clearly against the lighter base. All three share the same interchangeable strap system, which is a welcome touch.

Calibre 4404

Flipping any of the three 42 mm references over is well worth doing. Calibre 4404 is a selfwinding flyback chronograph movement, meaning the timing function resets and restarts in a single press rather than requiring multiple steps, and its architecture is on full display through the sapphire caseback. The column wheel and the 22-carat pink gold oscillating weight are both visible, and the quality of the finishing makes the view from the back almost as enjoyable as the view from the front.

The movement runs to 433 parts and 40 jewels, measures 32 mm in diameter and 8 mm in thickness, and delivers a guaranteed minimum power reserve of 70 hours at a frequency of 4 Hz.

The 37 mm Selfwinding Chronograph

The 37 mm Royal Oak Offshore Selfwinding Chronograph has been given a thorough refresh for summer 2026, and the results are genuinely exciting. Three new references arrive in titanium and 18-carat pink gold, with turquoise, pink and light blue leading the colour story. The case is slightly slimmer than previous models, fitted with a bezel curved from 6 to 12 o’clock, and the dial has been reworked with an enlarged Tapisserie pattern, new bathtub hands and luminescent hour-markers on the inner bezel. The date has also moved from 4:30 to 6 o’clock for a cleaner, more balanced dial layout.

The first reference is the turquoise titanium, a first for the 37 mm Offshore line. The turquoise Tapisserie dial, inner bezel and matching counters are finished with rhodium-toned numerals and 18-carat white gold hands carrying white luminescent material, and the rubber strap matches the dial colour perfectly. It is a fresh, three-toned design that works beautifully in the summer light.

The second stays in titanium but introduces a stainless steel bezel set with 32 brilliant-cut diamonds totalling approximately one carat, and a bright pink hue that runs from the dial through the inner bezel to the rubber strap. The luminescent hands and numerals keep legibility sharp throughout.

The third reference makes the move to 18-carat pink gold, also with a diamond-set bezel of approximately one carat, and a light blue Tapisserie dial with pink gold counters encircled in pink gold thread. The light blue rubber strap with a pink gold pin buckle completes the watch. All three references come with interchangeable rubber straps featuring the AP monogram moulded into the underside.

Calibre 6401

Calibre 6401 is the highlight of the 37 mm. Developed entirely in-house over five years, it replaces the longstanding Calibre 2385, a movement that had been a cornerstone of the manufacture’s offering since 1997. The new calibre is a selfwinding integrated column wheel chronograph equipped with Audemars Piguet’s patented vertical clutch system, which governs the synchronisation of the clutch levers and delivers a smoother, more responsive action with less pressure required on the push-pieces.

Flipping the watch over reveals the full picture. For the first time in the 37 mm Offshore line, the sapphire caseback now exposes the movement in its entirety, including the Côtes de Genève finishing, the alternating satin-brushed and polished surfaces and the dark grey NAC-coated 22-carat pink gold oscillating weight.

The calibre measures 27 mm in diameter and just 5.7 mm in thickness, runs to 350 parts and 44 jewels, and offers a guaranteed 55 hours of power reserve at 4 Hz. It is a genuinely impressive piece of watchmaking inside a watch that already has plenty going for it on the outside.

Offshore Diver

Originally introduced in its current 42 mm format in 2021, it is built specifically for underwater use, with a stainless steel case water-resistant to 300 m and two black ceramic screw-down crowns: one for setting the time, the other for controlling the internal rotating bezel. At 14.2 mm thick, it wears with a robustness that feels entirely appropriate for a watch designed with serious intent.

Three new colourways arrive for summer 2026, each distinguished by its treatment of the Méga Tapisserie dial and diving scale.

Two references feature a black dial with the 0 to 15-minute zone of the diving flange picked out in vivid colour. The first is pink, with turquoise on the second, featuring matching numerals on the rehaut. The colour choice here isnot only aesthetic, improving legibility in low-visibility conditions at depth.

Applied 18-carat white gold Diver indexes with luminescent coating and a date window at 3 o’clock complete the dial on both.

The third reference takes a different direction with a blue-green Méga Tapisserie dial and a white luminescent 0 to 15-minute zone on the diving scale. Rose gold accents appear in the dial details and on the crown, giving this reference a warmer character that sets it apart from the other two. White, turquoise and teal interchangeable rubber straps complete the set across all three.

Calibre 4308 powers every reference, running at 4 Hz with a guaranteed minimum power reserve of 60 hours. The blackened 22-carat rose gold oscillating weight is visible through the sapphire caseback and adds a satisfying finishing detail to a watch that earns its keep both above and below the waterline.
