Audemars Piguet's celebrations to mark the twenty-fifth anniversary of its legendary sports watch include the Royal Oak Offshore Tourbillon Chronograph in a bold and futuristic design which will be made available in two 50-piece limited editions in steel and rose gold.

With another man's defining classic ever present in the shadows, and a skeptical, hesitant management, a young designer was tasked to create a watch which would break new ground for the brand. No pressure then.

This unmistakable imposing profile reveals a brand new, hand wound stripped-back movement, as Audemars Piguet maintains a steady course with a stunning evolution of the Royal Oak Offshore Tourbillon Chronograph.

An undisputed design classic in its own right, the Royal Oak needs no introduction, and in truth design wise there are few changes to the much loved recipe, but foremost among those is the quite remarkable effect of the frosting technique on its rose gold case and bracelet.

It’s a luxury for any luxury brand to possess in their stable, a watch whose design is both ageless and timeless, and which has provided the basis for many variations, whilst still remaining unflinchingly true to its original drawings.

The Audemars Piguet Royal Oak Concept Supersonnerie is not simply a "chiming" watch, but rather a timepiece which houses a musical instrument in miniature within its sculpted watchcase.

With an upsized case and a new in-house calibre, the new Audemars Piguet Royal Oak Perpetual Calendar watch marks a significant addition to their portfolio.
