Less than a week later, the talking point for the brand – and maybe for the entire show – revolved around an Ultra-Thin Perpetual Calendar piece unique that synthesized the masculinity of a Royal Oak into a high-tech concept watch that measured in at 6.33 mm (for reference, your typical Jumbo comes in at 8.3 mm), making it the thinnest perpetual calendar in existence.

It’s also only the second R&D timepiece that Audemars Piguet has ever released. Not only does it have the great looks and iconic aesthetic that is associated with the Royal Oak, it is also revolutionary for the brand in many respects. AP was able to subsidize the watch from a three-story movement to a single one by combining various functions into single mechanisms. The brand was then able to shrink the rotor down to a minuscule 2.89 mm. Everything else about the watch, from the tapisserie dial, to the moon-phase at 12 o’clock (a throwback to the company’s first perpetual calendar wristwatch in 1955), is classic Royal Oak.
