Royal Oak Offshore 37 mm: Audemars Piguet injects fresh energy into its sporting icon

Some watches define their era. Others disrupt it. When Audemars Piguet unveiled the Royal Oak Offshore in 1993, the Le Brassus manufacture did far more than simply evolve the Royal Oak conceived twenty years earlier by Gérald Genta. It took the risk of transforming it radically.

Bigger, sportier, more assertive, the Offshore broke away from the luxury watchmaking codes of the early 1990s. At a time when discretion remained the norm, it laid claim to a strong, self-assured and almost provocative personality. The nickname it was quickly given, “The Beast”, perfectly captures its positioning.

More than three decades later, that original boldness continues to drive the collection. With three new 37 mm Royal Oak Offshore Selfwinding Chronographs, Audemars Piguet revisits its icon from a fresh angle, pairing next-generation mechanics with hues inspired by the most beautiful summer landscapes.

An evolution that goes well beyond a mere change of movement.

A new mechanical generation for the Royal Oak Offshore

Beneath their luminous colours, these new references mark the arrival of the Calibre 6401 in the 37 mm Royal Oak Offshore collection.

For Audemars Piguet, this is a significant milestone.

The Calibre 2385, which until now powered the chronographs of this family, had been part of the manufacture’s horological landscape for nearly thirty years. Replacing it was therefore no trivial matter.

Developed entirely in-house over five years, the new Calibre 6401 embodies Audemars Piguet’s contemporary vision of the chronograph. It retains the noble architecture of an integrated column-wheel chronograph with a vertical clutch, while benefiting from a completely rethought construction.

Smoother in use, more mechanically efficient and more robust over time, it also offers a 55-hour power reserve.

But the true novelty lies elsewhere.

For the first time, owners of a 37 mm Royal Oak Offshore Chronograph can admire the movement through a sapphire caseback. A window onto the manufacture’s mechanical universe that reveals the Côtes de Genève, the interplay of satin-brushed and polished surfaces, as well as an elegant 22-carat pink gold oscillating weight treated in dark grey NAC.

An evolution that may seem subtle on paper, yet is essential to the emotional experience the watch offers.

A more refined Offshore that loses none of its character

The Royal Oak Offshore has long cultivated the image of an imposing, assertive watch. That is precisely what made it a success.

Yet here Audemars Piguet has chosen to refine its design with subtlety.

The 37 mm case retains all the personality of the Offshore but adopts more fluid lines. The bezel now features a more harmonious curve, while the pushpiece guards blend more gently into the caseband.

The aim is not to turn the Offshore into a dress watch, but to enhance its comfort and ergonomics in everyday wear.

This philosophy is also reflected on the dial.

The Tapisserie pattern evolves with larger, more contemporary cells. The hands take on a new design, while the date moves to 6 o’clock, delivering a far more convincing visual balance.

Every detail appears to have been rethought with the same ambition: to modernise without distorting.

Titanium takes the stage

Among the three new models unveiled by Audemars Piguet, one stands out in particular.

The reference 26430TI.OO.A358CA.01 becomes the first 37 mm Royal Oak Offshore Selfwinding Chronograph crafted in titanium.

This choice of material profoundly changes how the watch is perceived on the wrist.

Lighter than steel while offering excellent resistance, titanium lends a more technical dimension to the Offshore. Paired with a turquoise dial and a matching rubber strap, it creates a watch that instantly evokes the world of water sports, regattas and Mediterranean summers.

This bold colour palette perfectly conveys Audemars Piguet’s desire to offer a more relaxed and more spontaneous Offshore.

When the diamond meets the sporting spirit

The other two references explore a different register.

The titanium version, fitted with a bezel set with 32 brilliant-cut diamonds, plays cleverly on contrasts. The robustness of the material is set against the brilliance of the precious stones, while the pink dial asserts a resolutely contemporary personality.

In contrast to the traditionally masculine codes that long accompanied the Offshore, this reference embraces a freer, more expressive approach to sporting luxury.

The third variation takes this approach even further.

Its 18-carat pink gold case, diamond-set bezel and light blue dial create a particularly successful dialogue between sophistication and ease. The whole evokes the soft colours of summer while retaining the distinctive presence of the Royal Oak Offshore.

A watch that perfectly illustrates the changing expectations of today’s clientele, increasingly drawn to versatility and personal expression.

The Offshore spirit, 2026 edition

What makes these new references particularly compelling is not only their aesthetics or their new movement.

Above all, they demonstrate Audemars Piguet’s ability to evolve one of its most emblematic collections without betraying its identity.

The Offshore remains that bold watch which refuses to compromise. It retains its sporting character, its immediately recognisable architecture and its strong visual presence.

But it gains in sophistication, comfort and mechanical refinement.

A natural evolution for a collection that, for more than thirty years, has accompanied the transformations of contemporary watchmaking without ever losing its pioneering spirit.

Passion Horlogère’s verdict

These new 37 mm Royal Oak Offshore Selfwinding Chronographs prove that an icon can evolve without losing its soul.

The arrival of the Calibre 6401 brings genuine technical added value, while the work carried out on the design noticeably improves the watch’s overall balance. As for the new colours, they breathe welcome freshness into a collection often associated with more classic hues.

Here Audemars Piguet delivers one of the most coherent evolutions of the Royal Oak Offshore in recent years.

A watch born to challenge convention which, more than thirty years after its creation, continues to do so with remarkable ease.
