The Nautilus collection was introduced in 1976. Patek Philippe was looking for a strong design and an inimitable personality. An inspiration for its design soon emerged: The universal shape of a porthole found on virtually all maritime vessels. The original model was the Ref. 3700/1 in steel. Since then, the Nautilus has established itself as a classic, elegant sports watch and the original reference is one of the most sought-after timepieces at auction. The new Nautilus collection showcases the flattering redesign of Patek Philippe’s casually elegant classic. It has gained style through subtle and carefully calculated changes while preserving its original spirit.
