Driven by the mechanical self-winding Caliber R CH 27 PS QI, this Grand Complications reference displays the day, date, month, leap year, and day/night indication through a series of apertures — a remarkable concentration of perpetual calendar information on a single dial. The 42mm rose gold case measures 15.11mm in height and features both an interchangeable full back and a sapphire-crystal case back, offering two distinct presentations. The case is humidity and dust protected.
The ebony black sunburst dial is anchored by an 18K gold dial plate, with gold applied hour markers lending warmth and legibility against the deep, dark ground. Every detail reflects the considered craftsmanship that defines the Grand Complications family.
The watch is worn on a matte black alligator strap with square scales, hand-stitched and secured with a fold-over clasp — a refined complement to the rose gold case that completes this sophisticated pairing.
