Fifty years after its debut, the Patek Philippe Nautilus is still the watch many collectors measure every luxury sports watch against. Its rounded octagonal bezel, the “ears” on each side of the case and the horizontally embossed dial are recognizable from across a room, and the collection now runs from simple time-and-date models to chronographs, annual calendars and a perpetual calendar. If you are thinking about buying one in this anniversary year, this Patek Philippe Nautilus buying guide covers the history, the key references, the 2026 limited editions and what to check before you buy pre-owned.<\/p>\n\n\n\n

A Steel Watch That Cost More Than Gold: The 1976 Original<\/h2>\n\n\n\n

The first Nautilus, reference 3700\/1A, appeared in 1976. It was designed by G\u00e9rald Genta, who had already drawn the Royal Oak for Audemars Piguet, and he based the case on the porthole of a transatlantic liner, with the side “ears” evoking the hinges of those watertight windows (Christie’s<\/a>). The name came from Captain Nemo’s submarine in Jules Verne’s Twenty Thousand Leagues Under the Sea. At 42 mm the case was unusually large for the period, which earned it the nickname “Jumbo,” and it was water resistant to 120 meters, a real challenge for a regular production watch at the time.<\/p>\n\n\n\n

It was also a gamble. As Patek Philippe Magazine<\/a> recounts, the Nautilus was a steel watch that cost more than a gold one, at a moment when thin quartz watches were in fashion. Philippe Stern, then taking over from his father, admitted he “was not quite convinced in the beginning,” but he saw it as a watch for a new, younger customer who traveled and played sports. Inside was calibre 28-255 C, based on a Jaeger-LeCoultre movement and finished by Patek Philippe (Forbes<\/a>). A ladies’ Nautilus followed in 1980, and a medium size arrived in the 1980s as well (Patek Philippe<\/a>).<\/p>\n\n\n\n

The Key Nautilus References to Know<\/h2>\n\n\n\n

Reference 5711: The Modern Icon<\/h3>\n\n\n\n

Launched in 2006 for the model’s 30th anniversary, the 5711\/1A updated the Nautilus with a 40 mm case, an exhibition caseback and an in-house self-winding movement with central seconds; late examples use calibre 26-330 S C (Phillips<\/a>). For years it was the most talked-about steel sports watch in the world. Patek Philippe discontinued the standard steel 5711 in January 2021, which pushed pre-owned prices sharply higher (CNBC<\/a>). Its final runs included an olive green dial and, at the end of 2021, 170 pieces with a Tiffany Blue dial celebrating 170 years of partnership with Tiffany & Co. The first of those sold at Phillips<\/a> in New York on December 11, 2021 for $6,503,500, with proceeds going to The Nature Conservancy.<\/p>\n\n\n\n

Reference 5811: The Successor<\/h3>\n\n\n\n

In October 2022 Patek Philippe introduced the 5811\/1G-001 in white gold. It keeps the familiar blue sunburst dial but grows to 41 mm, returns to a two-piece case in tribute to the original 3700, and uses calibre 26-330 S C in a case 8.2 mm thick (Horbiter<\/a>). If you love the 5711 look but prefer a current-production reference, this is the model to compare.<\/p>\n\n\n\n
