The original Patek Philippe Nautilus was launched in 1976 and the new Nautilus collection represents a modern interpretation, which retains many of the original design elements, including its defining porthole-inspired case shape. Although the watches in the collection share a clear aesthetic link, each model has its own unique features. For example, the Nautilus 5712 has a moon phase indicator, power reserve display and a date sub-dial, making it ideal for those who want easy access to plenty of information. Meanwhile, the Ladies Nautilus 7021 is a more showy timepiece, which is set with diamonds, features a stunning 18K gold dial plate and is sure to attract attention.
