The Patek Philippe Aquanaut Luce Annual Calendar Ref. 5261R-001, introduced on 27 March 2023, is the Aquanaut collection’s first annual calendar. Its calendar handles the varying lengths of 30- and 31-day months, but still requires a manual correction at the end of February each year. The rose-gold watch pairs that complication with an unusual display layout and a blue-gray Aquanaut-pattern dial.
What makes the 5261R notable?
Patek Philippe announced the Ref. 5261R-001 at Watches and Wonders Geneva in 2023 as the first annual calendar in the Aquanaut collection. It is also part of the brand’s effort to add complications to the Aquanaut Luce line. Patek Philippe describes the Luce, launched in 2004, as a feminine reinterpretation of the Aquanaut, which debuted in 1997. The 5261R is a non-gemset rose-gold model.
The release followed two complicated Luce references cited by Patek Philippe: the Travel Time Ref. 5269/200R-001 in 2021 and the “Rainbow” self-winding chronograph Ref. 7968/300R-001 in 2022. The 5261R adds an annual calendar rather than a travel-time or chronograph function.
How often does the annual calendar need adjustment?
The calendar shows the day, date and month. It automatically accommodates months with 30 or 31 days, but it does not account for February’s shorter length; the wearer must correct it once a year, at the end of February. Patek Philippe’s 27 March 2023 release describes it as “a complete day/date/month calendar requiring only one manual correction per year, at the end of February.” That is the manufacturer’s description of the mechanism.

How are the calendar and moon-phase displays arranged?
The indications are distributed around the dial rather than grouped in a conventional order: day at 3 o’clock, month at 9 o’clock, moon phases at 12 o’clock and the date in an aperture at 6 o’clock. Patek Philippe attributes this arrangement to the inversion of the calendar module in the case. Day and month are indicated by hands; the date appears in the lower aperture.

The case is rose gold and measures 39.9 mm across, measured by Patek Philippe at the 10–4 o’clock positions. It is 10.94 mm thick, has a sapphire-crystal case back and carries a published water-resistance rating of 30 m.

The design combines the collection’s recognizable patterned dial and strap with an additional calendar complication. Its distinguishing feature is not simply that it displays more information: the inverted module gives the day, month, date and moon phases their particular positions across the dial. Patek Philippe says its annual-calendar mechanism was invented and patented by the company in 1996; that is the manufacturer’s claim about the mechanism, not an independent assessment.
