The Swiss Manufacture of Haute Horlogerie launched two sets of Royal Oak Automatic 37 and 41 mm.

To celebrate the 50th anniversary of its iconic Royal Oak, two sets composed of ten automatic watches in white gold were launched. Each has been set entirely with a different baguette-cut gemstone so that between them they form a rainbow.

They are decorated with some 800 stones of the same hue, selected and cut to measure to offer intense and pure colors.

The setting is the work of Salanitro, a specialized partner of the Maison. Francois-Henry Bennahmias, CEO of Audemars Piguet, said: "This rainbow set is the perfect illustration of the excellent collaboration between partners, but also between talents working side by side to perpetuate the truly unique know-how of Switzerland".

Instead of playing with iridescent tones on a single watch, the Manufacture reinvented the rainbow in these ten-piece sets, each of which is decorated with a characteristic gem in a vivid hue: red, yellow, green, blue, purple, pink, and orange.

When designing the sets, it was essential to find the right stones, colors, and contrasts while meeting strict color and clarity criteria. The gems took a year to obtain and then underwent an exhaustive quality control process.

Ruby, emerald, and blue sapphire are the three queens of the gemstones that set the tone for chromatic gradation. To complement these colors, the gemology team brought the selection of stones rarely seen in the Haute Horlogerie industry: tanzanites, yellow chrysoberyls, pink tourmalines, amethysts, blue topazes, spessartines and tsavorites, all chosen for their bright colors and purity.

Both sets are animated by two automatic movements with hours, minutes, and seconds, without date display to give all the prominence to the setting of the dial.
