The Patek Philippe Ref. 5040R is one of the most elegant and distinctive executions of the perpetual calendar complication, housed in a beautifully curved tonneau shaped 18k rose gold case. Its proportions are graceful yet refined, offering a unique presence on the wrist while staying true to Patek Philippe’s understated design language. The dial features applied Breguet numerals, a signature of sophistication, and has developed a warm, attractive patina that enhances the vintage character of the watch. The layout includes day, date, month, moonphase, and leap year indication, clearly displayed without compromising the overall balance. Inside, the watch is powered by Patek’s renowned micro-rotor automatic movement, offering both technical sophistication and a slim profile. It is fitted with a Patek Philippe tang buckle, and offered as watch only. This Ref. 5040R represents a rare opportunity to own one of Patek Philippe’s most refined perpetual calendars, combining mechanical complexity, timeless aesthetics, and quiet rarity in a uniquely shaped case.
