Patek Philippe Nautilus Annual Calendar 5726/1A-014
Known as Nautilus Annual Calendar (steel, blue dial)
The 5726/1A-014 is the steel Nautilus Annual Calendar, the most complicated version of the collection you can get in full stainless steel without stepping up to a chronograph or a precious-metal case. Patek Philippe brought it out at Baselworld 2019 to replace the earlier 5726/1A-001 and 5726/1A-010, carrying over the same 40.5mm case and the same annual-calendar caliber but dressing it in a gradient blue dial with the collection's horizontal embossing and a black-shaded rim. What you get on the wrist is a proper everyday sports watch that also tells you the day, date and month across three apertures under 12 o'clock, runs a 24-hour subdial and a moon phase at 6, and only needs a single correction each year at the end of February. It is the Nautilus for the buyer who wants a complication that earns its keep, not just a date window. On 47th Street this is the steel Patek people ask for by name when they already own the 5711 and want the next thing.
Produced: Introduced at Baselworld 2019 and current in the Patek Philippe collection. It replaced the outgoing 5726/1A-001 (charcoal dial) and 5726/1A-010 (white dial), which were retired shortly before its launch.

Market & Value
Retail on the 5726/1A-014 sits around $45,930, but nobody is buying one at a boutique counter without a long relationship and a long wait, so the number that matters is the secondary market. Clean examples with box and papers have been trading in roughly the $120,000 to $160,000 band, with recent listings clustering around $130,000 to $155,000 depending on year, condition and whether the full set is present. WatchCharts data through mid-2026 shows the 5726/1A up about 26% over the trailing year, running ahead of the broader market, and it tends to sell in a little over a month when priced right. That combination of steel, an in-house annual calendar and Nautilus demand is why it holds a three-times-retail premium while a lot of other complicated pieces have softened. We track these prices because we write checks against them every week, not because a chart told us to.
What to Know Before You Buy
A few things a buyer should have straight before paying six figures. First, the -014 is the blue-dial successor, so if a seller shows you a charcoal or white dial they are quoting the earlier -001 or -010, which are different watches with different values. Second, this is an annual calendar, not a perpetual: it handles 30 and 31-day months on its own but needs one manual correction at the end of February each year, and the moon phase is accurate for 122 years before it drifts a day. Third, the caliber 324 base is a workhorse Patek has run for years, robust and serviceable, but that gold rotor and the annual-calendar module mean a proper service is not cheap, so factor it in on an older example. Fourth, condition on the integrated bracelet and the polished bezel edges is where value lives or dies on a steel Nautilus; over-polished cases lose the crisp facets that make the watch, and the market knows it. Always confirm the movement number, the dial reference and that box, papers and the extract match before money moves.
