Patek Philippe Nautilus 5800
This is the mid-sized Nautilus model from the second generation of the Nautilus family.
This legendary sports watch by Patek Philippe, designed by the famous watches designer Gérald Genta, in 1976 excited by its combination of luxury and stainless steel. Its design is inspired by the shape of ship portholes. The case is quite large but the thin case and integrated bracelet makes it wear smaller. Although known mainly as a steel watch, the Nautilus was also available in steel and gold, 18K yellow and white gold.
The case measures 38.4 mm (across the dial, from 9:00 to 3:00). Unlike the original Nautilus, with its straight hinge, the new Nautilus family is convex at the hinge and crown, matching the bezel. In all other members of the new Nautilus family, the case is composed of three main components rather than two as before. But the Nautilus 5800 remains at two parts, albeit with a sapphire crystal case back allowing the movement to be viewed, as on the short-lived 3711 and 3712. The side-mounted bezel screws remain, though they now form a "sandwich" with the case back rather than attaching to it directly.
The entire Nautilus family was replaced by Patek Philippe, with four new models introduced at a Geneva party held in November of 2006 to celebrate the 30th anniversary of the model. Launched that day were the simple 5711/1A, the mid-sized 5800, the 5712 Moon Phase, and the first-ever Nautilus chronograph, Ref. 5960. New to the collection are pink gold models and the introduction of optional leather straps rather than the traditional integrated bracelet.
The Nautilus 5800 was launched with Patek Philippe's in-house full-rotor automatic Calibre 330 SC AIG. This Ref. 5800 took over for the original Ref. 3800 in 2006 but was discontinued after only three years on the market.
