In 1932, Patek Philippe introduced the Calatrava, inspired by the iconic Bauhaus style. Since then, it has become the cornerstone of their collection and proudly stands as their flagship model. This 18k yellow gold version pays tribute to Patek Philippe’s original design, featuring a Clous de Paris (or "hobnail") bezel that adds a refined and distinguished touch. The case is in excellent condition, showcasing a lovely “oxidized” color and a beautifully shaped screw-down case back. Completing the timeless aesthetic is a white porcelain dial with black enamel Roman numerals and sleek black hands. This Calatrava is powered by a manual-winding movement, embodying the classic watchmaking tradition for which Patek Philippe is renowned. The movement has been fully serviced by our watchmaker. The watch is paired with its original, slightly used Patek Philippe strap and 18k yellow gold buckle. It also comes with the original certificate of origin, documenting its sale in 1995.
