In a period in which watchmaking was still linked to very classic and conservative stylistic canons, the hand of Gerald Genta - former designer of the Royal Oak by Audemars Piguet - created a model for Patek Philippe that over the years would become one of the most identifiable.
Thin lines and classic shapes were the cornerstones of watchmaking in the 1970s, a style linked to tradition that made the launch of such a different watch considered a gamble; especially for one of the most classic manufacturers such as Patek Philippe, associated by the public with round cases and complications rather than sports watches with shaped cases.
From the very beginning, the ambition was to create a piece of haute horlogerie with sporty features but still a bearer of the historical principles and values ​​of the Manufacture. A strong marine connotation, inspired by diving, is immediately identifiable both from the name "Nautilus" itself, from the case shaped like a ship's porthole and from a waterproof resistance up to 120 meters deep.
