Note: Some watches have achieved such a level of recognition among the collecting community that their designs are instantly recognizable and their names known even without associating them with the brand, examples include the Royal Oak, Speedmaster, Reverso, Daytona and of course the Nautilus to name a few. Originally introduced over 45 years ago, the Patek Philippe Nautilus redefined the meaning of luxury with the use of stainless steel for high-end wristwatches. Designed by Gerald Genta in 1976, supposedly just a few feet away from Patek Philippe executives, the Nautilus was inspired by the porthole of a ship built via a solid one-piece case with an octagonal bezel. Patek Philippe's original Nautilus 3700 "Jumbo" was discontinued in the mid-1980s and replaced by the smaller, more versatile reference 3800, which is the model we present here.
