Overview

Introduced as a limited edition of 200 pieces, the Royal Oak Perpetual Calendar Ultra-Thin features a 41 mm titanium case paired with a smoked blue dial. This model is an evolution of Audemars Piguet's groundbreaking RD#2 concept, which debuted in 2018 as the world's thinnest automatic perpetual calendar wristwatch. The watch's ultra-thin profile, measuring just 6.2 mm in thickness, houses the self-winding Caliber 5133 movement, a testament to the brand's innovative engineering. 

Design and Craftsmanship

The watch's aesthetic appeal lies in its harmonious blend of materials and meticulous attention to detail. The titanium case offers a lightweight yet robust structure, while the smoked blue dial adds depth and elegance. The dial features the traditional Royal Oak "Grande Tapisserie" pattern, enhancing its visual texture. White gold applied hour markers and Royal Oak hands with luminescent coating ensure optimal legibility. The integrated titanium bracelet, with its satin-brushed finish and polished bevels, exemplifies Audemars Piguet's commitment to superior craftsmanship. 

Movement and Performance

At the heart of this timepiece is the self-winding Caliber 5133 movement, renowned for its ultra-thin design and reliability. Operating at a frequency of 19,800 vibrations per hour, it offers a power reserve of approximately 40 hours. The movement's slim profile is achieved through innovative engineering, allowing for the integration of a perpetual calendar complication within an exceptionally thin caliber. The sapphire caseback reveals the movement's intricate finishing, showcasing Audemars Piguet's horological mastery. 

Features and Complications

The Royal Oak Perpetual Calendar Ultra-Thin is equipped with a perpetual calendar complication, displaying the day, date, month, astronomical moon, leap year, and day/night indications. This complex mechanism automatically accounts for varying month lengths and leap years, requiring no manual adjustment until 2100. Despite its complexity, the dial layout remains clean and legible, with sub-dials strategically placed for intuitive reading. The watch is water-resistant up to 20 meters, providing protection against minor water exposure.
