Patek Philippe Nautilus Annual Calendar Ref. 5726/1A-014, Stainless Steel, Blue Dial, 2020, Patek Philippe Service October 2026

In 1996 Patek Philippe invented a complication that no one had made before: the annual calendar. It knows the different lengths of the months and only needs to be corrected once a year, at the end of February. It is a smart, practical complication for everyday life, and in the Nautilus it found the perfect home. The 5726/1A-014 combines it with a steel bracelet and a blue dial, the color most closely tied to the Nautilus since 1976.

The 40.5 mm case is made of stainless steel and carries all the classic Nautilus details: the rounded octagonal bezel, the characteristic “ears” on the sides and the integrated steel bracelet with its alternating satin and polished links. It closes with a Nautilus folding clasp. Despite the complication, the watch stays comfortable and well balanced on the wrist.

The blue dial carries the horizontal embossed pattern every Nautilus fan loves, with a sunburst finish that brightens in the light and darkens toward the edges. The annual calendar is arranged in a clear and elegant way: the day, the date and the month appear in three windows, the moon phase sits at 6 o’clock, and a 24-hour indicator completes the display. The applied white gold markers and hands are filled with luminous material, so the watch stays readable at night.

Inside works the outstanding self-winding Patek Philippe caliber 324 S QA LU 24H/303 with a central rotor in 21 karat gold. You can admire it through the sapphire caseback.

The watch dates from 2020 and is in excellent condition. It was serviced by Patek Philippe in October 2026 and comes as a full set with box, papers, leather card holder, hang, tag, pin, and the service papers - october, 2026 - so you have full two ye<rs of Patek warranty!

"A cool and beautiful steel Nautilus with one of Patek Philippe’s smartest complications, freshly serviced by the manufacture.!"
