Representing one of the most celebrated perpetual calendars ever produced, the Patek Philippe Perpetual Calendar Ref. 3940J is a masterpiece of traditional Swiss haute horology. Introduced in the mid-1980s and revered by collectors worldwide, the second-generation Ref. 3940J showcases the elegance, technical excellence, and understated sophistication for which Patek Philippe is renowned. Crafted entirely from 18ct yellow gold and presented complete with its original box and papers, this exceptional timepiece remains one of the most important perpetual calendar references in the brand's history.
The beautifully proportioned 36mm case is crafted from solid 18ct yellow gold and houses a refined silver dial featuring the signature perpetual calendar display with day, month, leap year, 24-hour indication, date, and moonphase complication. Applied yellow gold baton hour markers and dauphine hands complement the timeless design, while the balanced layout offers remarkable legibility despite the complexity of the movement. Powering the watch is the legendary ultra-thin Patek Philippe Calibre 240 Q automatic movement, celebrated for its micro-rotor architecture, exceptional finishing, and enduring reliability. Paired with a luxurious leather strap and an 18ct yellow gold folding clasp, the Ref. 3940J exemplifies classical watchmaking at its finest.
