The Patek Philippe reference 4920 is one of the manufacture's most elegant Ladies' Calatrava models, combining timeless design with refined mechanical craftsmanship. Introduced in the early 2000s, the 4920 is distinguished by its graceful round case, beautifully proportioned profile and signature diamond-set bezel, offering a sophisticated interpretation of the classic Calatrava. Powered by the ultra-thin automatic Calibre 240, renowned for its micro-rotor construction and exceptional finishing, the watch displays central hours and minutes with a subsidiary seconds dial, delivering remarkable mechanical refinement within an elegantly slim case. Produced in white gold, yellow gold and rose gold, with a variety of dial colours, guilloché finishes and diamond-set configurations throughout its production, the 4920 has become one of Patek Philippe's most admired ladies' dress watch references, celebrated for its understated elegance, technical excellence and enduring expression of the Calatrava tradition.
