Patek Philippe Aquanaut Annual Calendar Moon Phases Rose Gold Blue-Gray Dial – 5261R-001

The Patek Philippe Aquanaut Annual Calendar ref. 5261R-001 features an opaline blue-gray dial with the signature embossed Aquanaut pattern housed in a 39.9mm rose gold case. Introduced as the first Annual Calendar Aquanaut, this self-winding timepiece combines sporty modern aesthetics with one of Patek Philippe’s most practical and refined calendar complications.

The day, date, and month are displayed in a balanced and highly legible layout, requiring only one manual adjustment per year. Paired with a moon phase complication and a matching blue-gray composite strap, the 5261R-001 represents a sophisticated evolution of the Aquanaut’s contemporary sporty-chic design language.

The Patek Philippe Aquanaut collection represents a modern interpretation of luxury sports watchmaking, combining contemporary design with the technical refinement of traditional Swiss haute horology. Introduced in 1997, the Aquanaut became known for its rounded octagonal case, embossed dial pattern, and durable composite strap designed for everyday versatility.

The Aquanaut Annual Calendar expands this identity by integrating one of Patek Philippe’s most practical complications, blending casual sporty elegance with high-level mechanical sophistication and everyday usability.
