Message on WhatsAppThe steel diamond-bezel 37mm is the entry point into gem-set Royal Oaks. It shares its case, movement and dial range with the plain-bezel 15550, and Audemars Piguet lists it without gendering it.
This Audemars Piguet Royal Oak Selfwinding wears a 37mm steel case with a light blue tapisserie dial under a diamond-set bezel. Calibre 5900 inside, on a steel bracelet.
Fun fact: calibre 5900 is 3.9mm thick, thinner than the 3120 it replaced, which is what let the 37mm case lose most of a millimetre in the 2022 redesign.
