Overview
The Patek Philippe Nautilus 5726/1A-001 unites the iconic porthole-inspired case of the Nautilus line with the practical sophistication of an annual calendar complication. Housed in a 40.5 mm stainless steel case and presented on the integrated Nautilus bracelet, it occupies a rare position as a sport watch capable of displaying the date, day, month, and a 24-hour indicator simultaneously. The black gradient dial, with its characteristic horizontal embossed pattern, gives the reference a distinctly refined yet athletic character.
History
The Nautilus line was conceived by Gérald Genta and introduced by Patek Philippe in 1976, establishing the template for the luxury sport watch genre. The 5726 reference extended that legacy by incorporating the annual calendar — a complication Patek Philippe patented in 1996 — into the Nautilus family. The 5726/1A-001 in stainless steel with a black gradient dial entered production around 2013 and remained in the catalogue for over a decade, becoming one of the most sought-after references in the modern Nautilus range before its discontinuation in 2024. Its long production run reflects both the enduring appeal of the Nautilus design and the practical elegance of the annual calendar function.
Notable points
- Calibre 324 S QA LU 24H is a self-winding movement incorporating an annual calendar that requires correction only once per year, at the end of February.
- The 40.5 mm stainless steel case follows the distinctive octagonal bezel and integrated bracelet architecture introduced with the original 1976 Nautilus.
- The black gradient dial features the horizontal embossed 'Clous de Paris'-style relief pattern that is a hallmark of the Nautilus aesthetic.
- A 24-hour subdial distinguishes day from night at a glance, complementing the annual calendar's day, date, and month displays.
- Produced from approximately 2013 to 2024, the reference enjoyed one of the longer continuous runs among modern complicated Nautilus references.
