The Patek Philippe Calatrava first launched in 1932. For its 85th birthday, Patek debuted the skeletonised Calatrava “Squelette” Ref. 5180/1R in rose gold 5N, the Calatrava Ref. 6006G in white gold with black dial, and the Calatrava “Azulejos” Ref. 5089G-061 and -062 (pictured below), with enamel dial designs inspired by glazed tiles used in Spain and Portugal. Meanwhile, the new Calatrava Haute Joaillerie Ref. 4899 offers a distinctly feminine mother-of-pearl dial, flanked by diamonds and rose sapphires.
