Here we come with the year 2018.
Following their Royal Oak Concept Acoustic Research timepiece from 2014, Audemars Piguet now created a new model for their Research & Development lineup. The replica Audemars Piguet Royal Oak RD#2 Perpetual Calendar Ultra-Thin is in fact now the thinnest automatic perpetual calendar in the world—and that’s a big deal.
The diameter of the familiar Royal Oak case shape measures 41mm and is crafted totally in platinum. Besides, the equally famous Royal Oak integrated bracelet is also in platinum, offering some famous weight on the wrist despite the watch’s record-breaking thinness. 
The blue “Tapisserie” dial features all the hallmarks of a perpetual calendar. There’s the moon phase indicator at 12 o’clock, the month subdial at 3 o’clock along with the leap year indicator underneath it, the date subdial at 6 o’clock, and finally, the day subdial at 9 o’clock along with a small day/night display below it.
The fake Audemars Piguet Royal Oak Offshore Grande Complication measures a hefty 44mm in diameter and the ceramic case consists of titanium pushers. The rubber strap emphasizes the replica watches sportiness while the minute repeater, perpetual calendar, and split-seconds chronograph functions remind us that AP is indeed an Haute horology manufacture. These types of complications are typically found in dressier more formal watches, but Audemars Piguet does have a habit of “breaking the rules”.
Audemars Piguet has revamped their famous “Tapisserie” dial with these new models, to now stream out from the tourbillon mechanism that sits at 6 o’clock rather than its traditional symmetrical layout. That layout surely brings the eye directly to the oscillating tourbillon—not that it needs it; the tourbillion is nicely capable of appealing all the attention on its own.
These new dials are encased within a 41mm octagonal RO case in stainless steel, pink gold, or platinum. The platinum version is further decorated with blue sapphires on the eight-sided bezel, sitting alongside the characteristic exposed screws. Powering the new Audemars Piguet Royal Oak Tourbillon Extra-Thin timepieces is the Caliber 2924, which can be admired via the see-through case back.
We end with a new iteration of an oldie. Based on the original 1972 Royal Oak, the new Audemars Piguet replica Jumbo Extra-Thin is now available in a complex of titanium and platinum.
