Patek Philippe introduced the Calatrava in 1932, post Art Deco with the Bauhaus principles in mind. With this model form following function has created a very cool, elegant watch that echos the design of the first Calatrava watches beautifully. A luxurious platinum case frames a simple and legible rose-gilt opaline dial with 'obus' style hour markers completing this effortlessly sheikh design. The beating heart of the watch is the equally iconic manually wound calibre, 30-255 PS with a reassuring 65 hour minimum power reserve.
