Perhaps the most iconic dress watch collection ever, the Patek Philippe Calatrava embodies the very essence of what a classically-styled timepiece should look like. Creating the entire dress watch niche in 1932 when it was released, the Calatrava has become a mainstay within Patek Philippe’s offerings, with the ref. 3602, launched in 1970s, standing as one of the defining Calatrava references of its time. Measuring 33mm in diameter, the ref. 3602’s 18kt white gold case features a Clous de Paris guilloche engraved bezel with thin elegant lugs that make it a wonderfully wearable watch, all features that have been retained by the modern Calatrava collection. With an understated porcelain-white dial with black Roman numerals complementing its complex bezel, the ref. 3602 is a masterclass in watchmaking craftsmanship that has resulted in a watch of the ages that provided Patek with the opportunity to launch new Calatrava variants inspired by its iconic design and aesthetic only recently. A rare watch at the best of times, the ref. 3602 is seldom seen in this particular configuration of 18kt white gold with a white dial, making it a true collector’s piece.
