In 2016, Patek Philippe is celebrating the 40th anniversary of its casually elegant Nautilus collection. For many aficionados and connoisseurs of classic watchmaking artistry, this is a memorable occasion as well. A look back to 1976 not only shows how quickly and dramatically the world has changed since then but also illustrates how well the Nautilus has stayed its course across four decades in terms of design, dependability, and popularity. With two limited-edition Nautilus 40th Anniversary models, the manufacture manifests its ability to keep pace with the times while preserving the key facets of a legend.
