The Patek Philippe Aquanaut Luce 5261R-001 is a sophisticated blend of sportiness and complication, introducing an annual calendar function to the Aquanaut collection. Crafted in 18k rose gold, its 39.9mm case maintains the signature rounded octagonal design, with a satin-brushed and polished finish that enhances its refined yet contemporary appeal. The blue-gray dial, embossed with the Aquanaut’s signature pattern, offers a striking contrast to the warm rose gold case, while applied gold numerals and hands with luminescent coating ensure excellent legibility.

At the heart of this timepiece is Patek Philippe’s self-winding Caliber 26-330 S QA LU, which powers the day, date, and month displays arranged in a balanced layout, along with a moon phase indicator at 6 o’clock. Unlike traditional annual calendars, this model features a sportier, more casual execution, making it both practical and luxurious. Paired with a matching blue-gray rubber strap, the Aquanaut Luce 5261R-001 is a versatile and elegant timepiece that combines Patek Philippe’s legendary craftsmanship with a modern, adventurous spirit.
