Pre-Owned Patek Philippe Patek Philippe Perpetual Calendar Moonphase Chronograph 'Salmon'

A perpetual calendar is like a small computer on your wrist.

Think of it this way: Imagine a watch that keeps track of not only the time, but also the date, the day of the week, and the month, tells you whether it’s a leap year or not, and what the current phase of the moon is. Oh, and one more thing — imagine it does all of this mechanically, using springs and gears, and that you only have to adjust it once every century or so. Crazy, right?

Patek Philippe likes to take this one step farther, however: In the early 1940s it released the model 1518, the first serially produced perpetual calendar chronograph, which combined the aforementioned qualities of the typical quantieme perpetuel with those of the chronograph for recording elapsed time. Since then, the firm has further cemented its place as the foremost watchmaker in the world with more QP chronograph models. 

The particular perpetual calendar chronograph, a Reference 5270P is no run of the mill perpetual calendar... Housed within the 41mm platinum case, it features an endlessly alluring salmon toned dial with applied blacked-gold indices and a matching feuille handset, a signed crown, a polished concave bezel, both a sapphire crystal and sapphire display caseback. Powered by the manually wound Patek Philippe Cal. CH 29-535 PS Q movement, it’s fitted to a lovely signed brown alligator leather strap with matching signed platinum deployant clasp. 

It would be enough to enjoy this innovative and stunning wristwatch on its own, but this particular timepiece also comes with its inner and outer boxes, books, leather folder, secondary solid platinum caseback, signed calendar corrector tool, and certificate of origin from Patek Philippe confirming its sale in 2022.

The combination of a white precious metal and a salmon dial is one of the most desirable configurations in fine Swiss watchmaking. Combined with its short production run, this piece not only embodies what a grail watch should be, but represents as close to a sure-thing as you can get in collectible high-end horology.

Any old wristwatch can tell the time. Very few truly define it.
