Patek Philippe Calatrava 5227G-001 is crafted in a 39mm white gold case with a polished finish and a hinged officer style case back that conceals a sapphire crystal. The dial features a lacquered black surface with applied white gold hour markers and dauphine hands, complemented by a date aperture at 3 o’clock. It is powered by the automatic Caliber 324 S C, operating at 28,800 vibrations per hour with a power reserve of approximately 35 to 45 hours. The movement includes a 21K gold rotor, Gyromax balance, and Spiromax balance spring, ensuring high precision and resistance to environmental variations.

This reference delivers a balance between classical design and modern usability, offering automatic convenience while preserving the clean identity of the Calatrava line. Its officer case construction adds a layer of exclusivity, making it particularly appealing to collectors who appreciate discreet complexity and refined finishing.
