Perpetual Calendar Bleu Nuit Nuage 50 Ceramic 41MM

ROYAL OAK PERPETUAL CALENDAR 26674CD – LEGENDARY BLUE ON HIGH-TECH CERAMIC

Like a quiet and deep micro-galaxy, this majestic timepiece shines brilliantly with its 41mm case crafted entirely from "Bleu Nuit, Nuage 50" ceramic. This iconic blue shade, a vital part of the Royal Oak's heritage since 1972, is now reborn on ultra-hard, highly scratch-resistant ceramic. The meticulous interplay of satin-brushed surfaces and highly polished bevels on the ceramic material requires hundreds of hours of dedicated work by the master artisans in Le Brassus. Combined with an ultra-light Titanium caseback, the architecture provides 50m of water resistance, ensuring eternal durability and supreme comfort on the wrist.

HARMONIOUS GRANDE TAPISSERIE DIAL AND PERPETUAL MECHANICS

The soul of this masterpiece resides in its "Bleu Nuit" dial adorned with the renowned Grande Tapisserie pattern, creating a powerfully elegant monochromatic presence. The dial layout perfectly orchestrates the perpetual calendar indications, including the day, date, month, leap year, week of the year, and a brilliantly detailed astronomical moon phase. The 18-carat white gold applied hour-markers and Royal Oak hands, treated with high-grade luminescent coating, act as guiding stars to guarantee absolute legibility under any lighting condition.
