The Patek Philippe Calatrava 3940G-011 is a classic and highly regarded perpetual calendar timepiece, housed in a 36mm 18k white gold case with an elegant opaline silver dial. The layout features day and month windows at 12 o’clock, a moonphase and date subdial at 6, and 24-hour and leap year indicators at 9 and 3 o’clock respectively.
Powered by the ultra-thin Caliber 240 Q with a micro-rotor, it offers a beautifully finished, self-winding movement visible through the sapphire caseback. The 3940G-011 remains a benchmark of Patek Philippe’s understated sophistication and technical mastery.
