The Patek Philippe Nautilus was designed in 1976 by Gerald Genta. Supposedly designed in 5 minutes, Genta drew his inspiration from the portholes of a ship. This nod to sailing was made as he knew the owners, the Stern family, had a love of sailing. This watch has remained one of the most desirable Patek Philippe designs for almost 5 decades. These watches are in such high demand that there is a waiting list of eight years from Patek Philippe, if you can even get on it. The value of the watches has risen substantially over the years and is unlikely to slow down as the Nautilus 5711 was discontinued with a new unique version being released due to demand. The dedication of the Stern family to the company and to maintaining the same level of quality almost guarantees the longevity of these watches.
