Audemars Piguet Royal Oak Perpetual Calendar replica, consisting of four new models in total: steel with a white or blue dial, and rose gold with a white or blue dial.
Audemars Piguet Royal Oak Perpetual Calendars, like the Royal Oaks that were launched in 2012, now come in larger, 41-mm-diameter cases. This new case size warranted a new movement (Caliber 5134), as well as offering more room on the dial with which to increase legibility and add a new function.
Audemars Piguet in-house Caliber 5134 is based on its predecessor, Caliber 2120. The automatic movement beats at frequency of 2.75Hz (19,800 vph), with 374 total parts, including 38 jewels, and a 40-hour power reserve. Movement thickness was kept to 4.31 mm, allowing the designers to maintain the thin case dimensions, which typically means a more comfortable fit on the wrist.
Technically speaking, the rose-gold, skeletonized oscillating weight, which can be custom-decorated upon a consumer’s request, is bidirectional, meaning it can wind the movement in both directions of motion. The balance has variable inertia blocks, a flat balance spring, and mobile stud-holder.
