Patek Philippe Aquanaut 5261R-001 39.9mm 26-330 S QA LU-Type Annual Calendar Watch
This Patek Philippe 39.9mm luxury sports watch combines a warm rose-gold-tone case with a blue-grey embossed dial and matching rubber strap. The balanced proportions create a refined and distinctive presence while remaining comfortable for everyday wear.
The dial features the Aquanaut-style geometric grid pattern, luminous Arabic numeral hour markers, and broad baton-shaped hands for clear reading. The calendar layout places the moon-phase display at 12 o’clock, the day at 3 o’clock, the month at 9 o’clock, and the date window at 6 o’clock, creating a symmetrical and practical display.
Powered by a 26-330 S QA LU-type automatic mechanical movement, the watch combines self-winding convenience with annual-calendar and moon-phase indications. A sapphire crystal protects the dial, while the transparent caseback provides a view of the mechanical movement inside.

FAQ
1. What does the annual calendar function do?
The annual calendar is designed to distinguish between months with 30 and 31 days. Under normal operation, it generally requires only one manual correction each year around the end of February.
2. How are the calendar indications arranged?
The moon phase is positioned at 12 o’clock, the day at 3 o’clock, the month at 9 o’clock, and the date window at 6 o’clock. This arrangement keeps the display balanced and easy to understand.
3. Can I adjust the calendar at any time?
Calendar adjustments should be avoided during the movement’s automatic date-change period, commonly around late evening and early morning. Forcing the correctors during this period may damage or misalign the calendar mechanism.
4. Is the 39.9mm case suitable for everyday wear?
Yes. The 39.9mm size offers a noticeable luxury-sports presence without feeling excessively oversized. The flexible rubber strap also helps the watch sit comfortably on a wide range of wrist sizes.
