The legendary Gerald Genta developed the Patek Philippe Nautilus collection in 1976. At its release, it was an innovation, featuring an unusually large case and striking octagonal case designed to resemble the oval-shaped portholes on the Submarine in the novel 20,000 Leagues Under the Sea . Today, the collection includes a variety of design options to suit nearly any wrist. Reference 5712G-001 with its lustrous white gold finish, slate grey dial, and Moonphase indicator is positioned as a serious investment for anyone who wishes to buy an iconic Patek. The Nautilus 40 we have in stock is certified pre-owned to protect your investment. Furthermore, it is in excellent used condition. Shop Patek Philippe Nautilus Collection
