To celebrate the 50th anniversary of its iconic Royal Oak, Audemars Piguet reinvents the traditional rainbow with the launch of two unprecedented Royal Oak Selfwinding sets in 37 and 41 mm, both illuminated by some of the most beautiful gemstones. The two sets are composed of ten white gold selfwinding hours, minutes and seconds timepieces, each entirely paved with a different baguette-cut gemstone so as to form a rainbow when all the pieces are put side by side. The different watches are adorned with some 800 baguette-cut coloured stones of the exact same hue, all meticulously selected and custom-cut to offer intense and pure colours. The gemsetting was accomplished by long-time partner Salanitro, a company specialised in watch manufacturing and stone setting.
