Patek Philippe Calatrava 3940G-011 Perpetual Calendar Moonphase White Gold Opaline Silver Dial

Description

The Patek Philippe Calatrava 3940G-011 is one of the most iconic perpetual calendar wristwatches in modern horology. First introduced in 1985 and discontinued in the mid-2000s, the 3940 series exemplifies Patek Philippe’s philosophy of timeless design, mechanical ingenuity, and understated elegance. The 3940G-011, housed in 18k white gold with an opaline silver dial, represents a later, highly refined execution of this legendary reference.

The 36mm case is ultra-slim and beautifully proportioned, with softly curved lugs and a domed bezel that evokes classic Calatrava aesthetics. The polished white gold surfaces add just enough presence, while maintaining the quiet restraint that defines Patek Philippe’s perpetual calendar lineage. At under 9mm thick, it slips effortlessly under a cuff—making it one of the most elegant high-complication watches ever produced.

The three-register dial layout is a masterclass in symmetry and balance. At 3 o’clock, the month and leap year are displayed; at 9 o’clock, the day of the week and 24-hour indication; and at 6 o’clock, the date and moon phase. The opaline silver dial is clean and beautifully finished, with applied white gold dauphine hands and hour markers. Black printed scales and crisp subdials make the information-rich display intuitive and legible.

Inside beats the legendary Caliber 240 Q, a self-winding movement with micro-rotor architecture—a technical hallmark of Patek Philippe’s ultra-thin complicated watches. This beautifully finished movement features Geneva stripes, polished bevels, and perlage, all visible through the sapphire crystal caseback. Despite its complexity, the Caliber 240 Q maintains a svelte form, allowing the 3940 to remain elegant on the wrist while tracking time, date, day, month, leap year, and moon phase accurately through the year 2100.

The watch is paired with a classic hand-stitched black alligator strap and secured by an 18k white gold Patek Philippe deployant clasp.

The Patek Philippe 3940G-011 is more than a perpetual calendar—it is one of the most revered references in the brand’s modern history. Its compact size, mechanical finesse, and design purity make it a cornerstone in any serious collection of haute horlogerie.
