The Patek Philippe Complication Perpetual Calendar reference 5940R-001 presents a distinguished aesthetic defined by its tonneau-shaped case, a relatively rare form within the brand’s catalog. Crafted from 18k rose gold, the 37mm by 44.6mm case exhibits a refined profile with highly polished surfaces that transition seamlessly to the satin-finished caseband. The white dial provides exceptional legibility for its complex functions, featuring applied Breguet-style gold numerals and chemin-de-fer minute track. The subsidiary dials for the day, month, date, and moon phase are arranged in a balanced, symmetrical layout. This example is fitted with a new brown crocodile leather strap, which complements the warm tones of the rose gold case and lugs. Powering this watch is the self-winding Caliber 240 Q, a movement renowned for its reliability and ultra-slim profile. The perpetual calendar mechanism is a notable complication, automatically accounting for the varying lengths of months and leap years until the year 2100. The 24-hour display and moon phase aperture are integrated into the date sub-dial at 6 o’clock. The movement’s finishing is meticulous, visible through the sapphire case back, featuring Geneva striping on the bridges, chamfered edges, and a 22k gold mini-rotor. This technical execution ensures the watch functions with precision while maintaining a slender case thickness. This specific timepiece is in mint condition, showing no visible signs of wear, and is accompanied by its original papers. The presence of complete documentation is a critical factor for collectors, confirming the watch’s authenticity and provenance. The reference 5940R-001 occupies a significant position in the market as Patek Philippe’s first self-winding perpetual calendar in a tonneau case, making it a historically important model. Its combination of a classic complication with a distinctive case shape and excellent condition makes it an exemplary and highly collectible piece, likely to maintain its value and appeal to serious collectors of complicated Patek Philippe watches.
