This new line of Royal Oak Offshore in a 43mm case size, comprising five models in stainless steel, pink gold or titanium, is the first refresh of the collection since the 44mm diameter that was released in the early 2000s. While retaining all of the model’s distinctive characteristics, a subtle reworking of the case and dial introduces a fresh aesthetic, in particular the revamped Mega Tapisserie pattern, and a more refined, ergonomic shape. Making its debut in the Royal Oak Offshore collection is Calibre 4401: Audemars Piguet’s latest integrated flyback Chronograph with column wheel and vertical clutch to prevent stuttering of the chronograph hand when activated. Straps can be swapped in and out thanks to the new interchangeable strap system.
