Patek Philippe Complications 5172G-001 Chronograph has redesigned its chronograph of classic architecture for men (column wheel, horizontal clutch and manual winding), endowing it with a new white gold case with round guilloche pushers and three-tier lugs. Its subtle vintage allure is underscored by a sapphire-crystal “box” glass. The dial also sports an all-new look with a blue background and contrast luminescent white gold applied Arabic numerals and hands.
