Audemars Piguet introduced the Replica Royal Oak RD#2 Perpetual Calendar Ultra-Thin, a concept watch that claimed the title of being the world’s thinnest automatic timepiece featuring a perpetual calendar.

While the dial color — and matching subdials — remains an attractive shade of blue, AP has applied a detailed satin finish to the watch’s face. Optimized readability was key for Audemars Piguet Replica with this release, so the day, date, and month subdials were all enlarged compared to previous RO Perpetual Calendar models, like the Ref. 26574.

Where the Audemars Piguet Replica Watches China was constructed entirely from 950 platinum, AP has combined titanium and platinum in the finalized version for enhanced wearability. The bracelet and case are made from titanium, while the bezel and bracelet links are built from 950 platinum.

The more standard Royal Oak Perpetual Calendar models use the same base caliber for Caliber 5134, the taller predecessor to this year’s ultra-thin release. While it’s not apparent from the outside, AP Replica Watches Iced Out had to stretch the dimensions of Caliber 5133, which measures 32 mm compared to 29 mm in Caliber 5134, to counteract the shrinkage in height.
