Nautilus 3800A | 37 mm | 2003 | Original box | Original papers The Patek Philippe Nautilus 3800/1A-001 was introduced in the early 1980s as a mid-sized evolution of the legendary Nautilus 3700, the Maison’s first luxury sports watch designed by Gérald Genta in 1976. Retaining the signature porthole case and softened octagonal bezel, this 37.5 mm model offered a more wearable and versatile option while preserving the original Nautilus spirit. The case and integrated bracelet are crafted in polished and brushed stainless steel, with finishing executed to the highest standards. The black dial, protected by sapphire crystal, features applied Roman numerals — a distinctive element compared to most Nautilus models — and a date window at 3 o’clock. Its aesthetic is refined yet functional, blending classical elegance with a sporty character. Powered by the self-winding calibre 330 SC with central rotor, it offers hours, minutes, seconds and date with mechanical refinement and robust performance. The movement is certified with the Geneva Seal, a mark of superior finishing and control. Now discontinued, the 3800/1A-001 is highly sought after by collectors for its balance of compact dimensions, historical relevance and design continuity within the Nautilus family.
