The Patek Philippe Calatrava Clous de Paris White Gold Grey Dial 39mm Ref. 6119G-001 pairs classic design with modern engineering in a refined 39mm white gold case, launched in 2021. This Calatrava features a distinctive guilloched hobnail-pattern bezel and a charcoal grey dial with vertical satin finishing. Faceted, applied white gold obus-style hour markers and dauphine-style hands ensure precise legibility and a streamlined look. The manual-winding calibre 30-255 PS movement delivers a robust 65-hour power reserve, with a small seconds subdial adding functional detail. At just 8.08mm thick, the case maintains a slim profile, and the sapphire case back offers a view of the meticulously finished movement. The watch is water-resistant to 30 meters and comes fitted with a shiny black alligator leather strap secured by a white gold prong buckle. The Calatrava 6119G-001 stands out for its blend of traditional finishing and contemporary mechanical performance.
