The Audemars Piguet Royal Oak has since its very beginning continued to convert - at first slowly, and among more than a raised eyebrow, but with increased momentum since the 1990s - more and more enthusiasts to its cause. In the past year and a half, however, the yearly inflow of new adepts has turned into a true tsunami. Following a pattern similar to the one seen with other sports watches (most notably the Rolex Daytona and the Patek Philippe Nautilus) a few years earlier, the watch collecting community collectively took conscience of both the importance and the scarcity of the iconic Royal Oak, and its variants. Most notably, perpetual calendars Royal Oak timepieces have soared to the top of the collector’s wish-lists, and for good reason. They combine one of the ultimate horological complications with one of the most iconic designs. They are intimately tied with the Royal Oak line, having been realized since the late 1980s (for a comparison, the first perpetual calendar Nautilus appeared on the market in 2018). Their aesthetic appeal is undeniable as is their scarcity. However, within the few pieces made, Audemars Piguet showed remarkable creativity, and produced a number of different variations in terms of case metal and of dial design, as exemplified by the present watch.
