Patek Philippe is marking the 50th anniversary of the Nautilus with a series of limited-edition releases, including a rare desk clock and updated “Jumbo” and “Medium” models. The collection features the Calibre 240 automatic extra-flat movement and a new manual-wind calibre 31-505 8J PS IRM CI J for the desk piece, according to official brand specifications.
Why does the Nautilus design remain a benchmark in luxury sports watches?
The Nautilus’s enduring appeal stems from Gérald Genta’s original 1976 design, which prioritized technical function over purely artistic whim. Patek Philippe states the case was engineered to be water-resistant to 120 meters, utilizing a two-piece construction inspired by ship portholes. This design uses two hinges—the “ears”—and four clamping screws to create a hermetic seal against the steel frame.
Unlike the conservative, round, or rectangular watches dominant in the mid-70s, the Nautilus introduced a 42mm diameter and an integrated bracelet. This established the “sport chic” category, blending the robustness of a tool watch with high-end finishes. The brand achieves this by alternating polished and satin surfaces on the case and using a horizontally embossed dial.
What are the specific 50th Anniversary limited editions?
Patek Philippe has released four distinct versions to celebrate the milestone. These include two “Jumbo” models at 41mm: one in grey gold with a metal bracelet (Ref. 5810/1G-001, limited to 2’000 pieces) and one in grey gold with a composite bracelet (Ref. 5810G-001, limited to 1’000 pieces).
A “Medium” 38mm version in platinum (Ref. 5610/1P-001) is also available, limited to 2’000 pieces. The most unconventional addition is a grey gold desk clock (Ref. 958G-001), limited to just 100 pieces. This 50.65mm piece features a manual-wind calibre launched in 2025 and an eight-day power reserve with a ninth “reserve” day.

How does the movement affect the watch’s profile?
The wrist-worn anniversary models utilize the Calibre 240, an ultra-thin automatic movement. At only 2.53mm thick, this calibre allows the overall case thickness to be reduced to 6.9mm. This maintains the original 1976 silhouette while improving wearer comfort.
The movement features a 22ct gold mini-rotor, which in these limited editions is engraved with “50 1976-2026.” This technical choice ensures that the watch remains slim despite the complexity of the automatic winding system.
What features define the new desk clock?
The Ref. 958G-001 desk clock translates the Nautilus aesthetic into a stationary object. It includes an instantaneous date pointer, a day window, a small second hand at 6 o’clock, and an 8-day power reserve indicator. According to Patek Philippe, the piece uses a hinge system for the back cover, which also serves as a support for the clock.
The clock’s design incorporates a blue “sunburst” finish and horizontal relief, protected by sapphire glass and adorned with the Calatrava cross. The movement is visible under a second sapphire crystal, showcasing the manual-wind calibre 31-505 8J PS IRM CI J.
Frequently Asked Questions
What is the significance of the “ears” on a Nautilus?
The “ears” are hinges that compress the bezel against the case, ensuring the watch remains water-resistant, mimicking the locking mechanism of a ship’s porthole.
What is the difference between the two Jumbo 50th anniversary models?
While both are 41mm in grey gold, the 5810/1G-001 has a metal bracelet, whereas the 5810G-001 features a composite bracelet and baguette diamond-set indices.
How thin is the anniversary Nautilus case?
Thanks to the 2.53mm Calibre 240 movement, the case thickness is only 6.9mm.
