The high-performance Aquanaut Luce Annual Calendar Ref. 5261R-001 stands out with its unique design and advanced technology. This watch uses a 39.9 mm diameter case, is equipped with a new 26-330 S QA LU self-winding movement, is equipped with a 21K gold central automatic disk, and is equipped with an annual calendar device with a moon phase display.
The watch’s calendar display is innovative and presents the annual calendar device in reverse, making it unique among Patek Philippe timepieces equipped with an annual calendar display. The date and moon phase windows are set at 6 o’clock and 12 o’clock respectively, while the auxiliary dials for the day and month are located at 3 o’clock and 9 o’clock respectively. This design not only facilitates quick reading of time, but also adds unique charm to the watch.
The moon phase display is particularly accurate on the Aquanaut Luce annual calendar watch, which only deviates from the actual lunar cycle by one day every 122 years. This high degree of accuracy demonstrates Patek Philippe’s pursuit of excellence in watchmaking craftsmanship, making the watch a treasure sought after by watch collectors and fashion enthusiasts. The Aquanaut Luce Annual Calendar Watch Ref. 5261R-001, with its unique appearance and exquisite mechanical design, has become an outstanding interpretation of Patek Philippe’s tradition of excellence.
The 26-330 S QA LU movement is based on the 26-330 movement. The movement made its debut in 2019 and was initially installed in the Calatrava weekly calendar watch Ref. 5212A-001. It has been infused with a number of innovative technologies and optimization functions to ensure excellent performance and reliable quality. Among them, the patented anti-backlash wheel is an important innovation, used to suppress the vibration of the second hand; in addition, the application of the patented clutch wheel improves the efficiency of the automatic winding device and extends its service life.
This movement also introduces a “stop seconds” function. By pulling the crown to the manual adjustment position, the balance wheel can be paused to ensure that the time adjustment is accurate to the second. When the wearer pushes the crown back into place, this device provides a slight power to the balance wheel, restarting the movement of the movement.
With its advanced technology and innovative functions, the 26-330 S QA LU movement provides reliable power support for the Aquanaut Luce Annual Calendar Watch Ref. 5261R-001, further highlighting Patek Philippe’s excellent craftsmanship in the field of mechanical watchmaking.
The Aquanaut Luce women’s watch series debuted in 2004 and is a new interpretation of the Aquanaut series launched in 1997. Since its inception, this series has been committed to launching ingenious timepiece masterpieces, injecting new vitality into the field of watches.
Among them, the stainless steel watches Ref. 5267/200A-001, Ref. 5267/200A-010 and Ref. 5267/200A-011 equipped with quartz movements are one of the highlights of the Aquanaut Luce series, offering a variety of dial colors and same-color series. The choice of watch straps provides women with more fashion matching possibilities. In addition, the rose gold self-winding watch Ref. 5268/200R-010 is equipped with a taupe dial and an integrated connecting strap, showing a unique design charm.
The Aquanaut Luce series not only focuses on fashion, but also makes breakthroughs in the field of high-end jewelry watches. Ref. 5062/450R-001 adopts superb jewelry inlay technology, showing excellent craftsmanship and luxurious design. The Ref. 5072R-001 is set with baguette diamonds on the bezel and paired with a two-color engraved mother-of-pearl dial, providing women with a more noble and elegant choice.

This exquisite shade first appeared in the Aquanaut Luce stainless steel model Ref. 5067A-025 released in 2018-2019, and achieved great popularity among female watch enthusiasts. The Aquanaut embossed pattern on the dial complements the rose gold three-dimensional Arabic numerals and baton-style hands, all covered with white fluorescent coating, making the time reading clearer.
