Launched in 1932, the Patek Philippe Calatrava collection saw minimal variations over the years and is regarded as the flagship model of the most esteemed watchmaker in the world. The Calatrava is available in a classic gold or platinum round case and sports an elegant array of straps and bracelets. The watch features a flawlessly clean dial with bezels that come as either smooth, adorned with diamonds, or with the signature hobnail pattern. Other than basic time functions, several models also feature a second subdial, date in aperture, or a dual time zone display, powered by either a hand-wound or automatic movement. Recognized as the epitome of precision and reliability in horology, the Patek Philippe Calatrava is the one timepiece that is definitely handed down from one generation to the next.
