Audemars Piguet’s two gem-set Royal Oak Selfwinding 37mm versions pair 18-carat gold with contrasting dials and stone settings: pink gold with a light-blue dial and blue-sapphire bezel, and white gold with a light-green dial and diamonds across the case and bezel. Their references are 15551OR.ZS.D344CR.01 and 15551BC.ZZ.D405CR.01, respectively.
How the two references differ
The launch report identifies these as two specific 37mm Royal Oak Selfwinding references—not just color variations of one watch. Audemars Piguet’s collection listing also places both references in the Royal Oak Selfwinding 37mm family and identifies their respective gold materials (Audemars Piguet’s Royal Oak collection).

Each is powered by the automatic Calibre 5900. The launch report gives its specifications as 188 components, 29 jewels, a 3.9mm height, a frequency of 28,800 vibrations per hour (4Hz), and a 60-hour power reserve. It also reports 50m water resistance for both watches.
Design changes described in the launch coverage
Monochrome places these models in the Royal Oak 37mm design’s evolution after 2022. It describes a 9mm-thick case, compared with a previous 9.8mm profile, along with more pronounced polished bevels and bracelet links that are thinner and lighter. The article also notes a printed minutes track on the Grande Tapisserie dial and a date-window background matched to the dial color. These historical design comparisons are the launch article’s account; the AP collection listing confirms the model family and gold materials but does not independently establish every comparison.
