Of all the complications in existence, Patek Philippe is perhaps associated the most with the perpetual calendar.

In fact, it was Patek Philippe that for the first time integrated this highly complex mechanism in a watch that could be worn on the wrist in 1925. Since then, Patek has released a wonderful line-up of slim and classy dress watches with a perpetual calendar complication. 

The ref. 5140 was introduced in 2006 as the modern reinterpretation of the perpetual calendar wristwatch. Compared to its predecessor, the venerable ref. 3940, the 5140 featured a larger case, measuring in at a slightly larger 37 mm, giving this classic watch a more contemporary vibe.

This ref. 5140G dates back to 2011 and is executed in an 18K white gold case. The case sports a sapphire see-through case back, yielding an uncensored view of the expertly finished ultra-thin automatic movement with a 21K yellow gold micro rotor.

The classic opaline dial features applied 18K white gold baton markers and elegant 18K white gold dauphine hands. The lovely recessed sub-register at the 9 o’clock position displays the days of the week and a handy 24-hour counter, while the month and the position in the leap-year cycle can be read off of the sub-register at 3. Finally, the lower sub-register incorporates a romantic moonphase indicator that is surrounded by the date functionality.

This exceptional perpetual calendar wrist watch is in excellent condition and comes on a black alligator leather Patek Philippe strap with an 18K white gold Patek Philippe deployant clasp. The watch has just returned from a full service at our trusted Patek Philippe service center and comes with the corresponding service papers and an extract of the Patek Philippe archives.
