Outstanding design. Exceptional brand recognition. Optimal Precision. Unparalleled resale value. The list goes on. The iconic model is now available in a palette of blue tones, exuding an ultra-feminine allure.The softly rounded contours of the white gold case are set with staggered rows of diamonds, interspersed with sapphires in varying intensities of color.On the lower part of the dial, diamonds mingle with blue sapphires in a “random” or “snow” setting, while the upper part, in mother-of-pearl, features a hand-engraved feather motif in delicate blue tints.The Calatrava is one of the defining models of the Patek Philippe brand. They released the first men’s model in 1932 and the first ladies’ model several decades later. This model displays basic hours and minutes and boasts water resistance up to 30 meters.
