Launched in 1972, the Blue Dial Audemars Piguet Royal Oak Perpetual Calendar replica watch was the first luxury watch to treat stainless steel, and meticulously craft, polish and decorate it, like a precious metal. Since then, this iconic line has been offering exceptional timepieces by incorporating traditional and unconventional materials like platinum, carbon, alacrite, bronze, rubber, ceramic, titanium, tantalum, etc… The essential leap year indication, an Audemars Piguet innovation first introduced to wristwatch design in 1955, takes centre stage at noon. An astronomical moon finds it place at six o’clock, and the week of the year is displayed on the dial’s outer chapter ring, adding yet another layer of time measurement.
Part of the inspiration for this new edition is the first Royal Oak Perpetual Calendar (reference 5554, later renamed 25554), designed by Jacqueline Dimier in 1984. Of the 279 pieces in that original launch, 229 were sumptuously cased in yellow gold.
Housed in the perpetual beauty of yellow gold, the self-winding Royal Oak watch’s new calibre 5134 is fully visible through the glare proof sapphire crystal caseback, but the warm, natural glow of precious gold has been brought fully to the fore. Calibre 5134 is based on its predecessor, calibre 2120, however it has been enlarged to perfectly fit the updated 41mm case size.
On the “Grande Tapisserie” decorated dials — a subtle pattern of three-dimensional squares— the traditional displays of a perpetual calendar timepiece are given pride of place: day, month and date are displayed at nine, noon and three o’clock.
