On the occasion of the Nautilus’ 50th anniversary, Patek Philippe presented a series of anniversary references, led by the Patek Philippe Nautilus 5810/1G-001 and the Patek Philippe Nautilus 5610/1P-001. At first glance, the two seem almost interchangeable. Both share the same deep blue horizontally embossed dial, the same ultra thin profile, and the same decision to strip the display back to hours and minutes alone, with no seconds hand or date to interrupt the balance. Yet despite this similarity, they represent two distinct interpretations of the Nautilus, shaped not by complication, but by proportion and material.

Patek Philippe Nautilus 5810/1G vs 5610/1P: 50th Anniversary Comparison
BY ONARO
The most immediate distinction is size. The 5810/1G measures 41mm, placing it firmly within the modern Nautilus language and aligning with what collectors have come to expect over the past decade, carrying a broader stance and a sense of familiarity on the wrist. The 5610/1P, by contrast, comes in at 38mm, and while the difference may appear modest on paper, it shifts the character of the watch entirely. The proportions feel closer to earlier Nautilus references, more compact and more restrained, without directly replicating them. Both remain just under 7mm in height, though their presence is defined far more by diameter than thickness. Material reinforces this difference. The 5810/1G, crafted in white gold, preserves the visual identity of the Nautilus and can easily pass for steel at a glance, allowing the design itself to remain the focus, with its weight revealing itself more gradually over time. The 5610/1P, executed in platinum, takes a different direction, introducing a noticeable density and a cooler, more subdued tone, along with the small diamond set into the case at 9 o’clock, a discreet detail that signals its material to those familiar with the brand.
Both references are defined as much by what has been removed as by what remains. By eliminating the seconds hand and date, the focus shifts away from function and toward proportion, finishing, and the structure of the watch itself. The dial becomes more expressive as a result, its horizontal embossing catching light in a way that would be less apparent on a more complex layout. That clarity is supported by the movement, but also by everything built around it. At the centre sits the calibre 240, an ultra thin automatic movement introduced in 1977, during a period when mechanical watchmaking was being forced to rethink its direction. Rather than respond with added complexity, Patek Philippe focused on proportion, developing a self winding movement that could preserve the elegance of a slim case without compromising practicality. Measuring just 2.53mm in height, it achieves this through a recessed 22k gold micro rotor integrated within the movement rather than mounted above it, removing an entire layer of height compared to a conventional automatic construction.
There is also a broader challenge behind this. Reducing height in watchmaking often introduces trade offs in durability, power reserve, and stability, requiring tighter tolerances, more precise assembly, and careful control of energy. The calibre 240 addresses this through its micro rotor, which, despite its smaller size, is crafted in dense 22k gold to maintain efficient winding. The result, in both the 5810/1G and 5610/1P, is a watch that remains just under 7mm in height, even in white gold and platinum, not because of a single feature, but because every element is aligned around preserving proportion.
The existence of both the 5810/1G and 5610/1P also reflects how the Nautilus has evolved under Thierry Stern. Since taking over Patek Philippe in 2009, Stern has taken a far more active approach to reshaping the collection, from discontinuing the immensely successful Patek Philippe Nautilus 5711 at the height of its demand to introducing bolder proportions, precious metals, and more assertive interpretations of the Nautilus concept. The 5810/1G and 5610/1P capture that shift particularly well. Despite sharing the same stripped back architecture, they show how the Nautilus now moves in two directions at once, one leaning further into the larger, more contemporary identity the collection has developed over the past decade, the other returning toward the smaller, more restrained proportions that defined earlier references.
On the wrist, the difference becomes clearer. The 5810/1G feels familiar, its size and weight close to what many expect from a modern Nautilus, while the 5610/1P feels more deliberate, with platinum adding a density that changes how the watch sits and how it is experienced over time. Both were introduced as part of the anniversary and produced in limited numbers, yet they do not compete with one another. The 5810/1G continues the Nautilus in its current form, while the 5610/1P offers a more compact and materially distinct interpretation. In the end, the distinction is straightforward. Same watch in concept, but not in feel.
