Ladies and gentleman, may we present the new Audemars Piguet Royal Oak ref. 15400 in stainless steel and 18K rose gold. This novelty marks the return of one of our all-time favorite Royal Oaks phased out in the 1990s and originally launched under reference 5402SA as a 'Two-Tone' Royal Oak Jumbo in 1976. The Audemars Piguet Royal Oak Jumbo 'Two-Tone' ref. 5402SA was only produced for a few years and only 951 were ever created. This new watch highly reminiscent of its predecessor will be available in 41 mm and in a 33 mm ladies size with diamond encrusted bezel. Later today, we will bring you more pictures and our full review with wristshot of this new timepiece.
