Patek Philippe Tonneau Perpetual Calendar

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 has been making such timepieces since the Second World War, and continues to make some of the most superlative quantieme perpetuelles on the market. This particular example, a Reference 5040P from the 2010s, is a spectacularly elegant model in an offbeat, tonneau-shaped case that remains understated despite its highly complicated nature.

Magnifique! 

Housed in a 39mm platinum case with a signed crown, a sapphire crystal, and a smooth bezel, it features a silver dial with applied, white gold ‘Breguet’ numerals, a matching ‘Breguet’ handset, and an outer ‘railroad’ minute track. Calendar indications include a month and leap-year sundial at 3 o’clock, a date and moonphase aperture at 6 o’clock, and a day and 24-hour sundial at 9 o’clock, all of which is powered by the automatic Patek Philippe Calibre 240 Q. (The magnificent movement architecture, you’ll be delighted to know, is viewable via a transparent sapphire caseback.)

Paired to a signed, black alligator leather strap with a signed, platinum pin buckle, this magnificent QP is a sophisticated masterwork of haute horlogerie — in other words, it’s precisely the type of watch you want from as storied and important a watchmaker as Patek Philippe! 

Founded in 1839, Patek Philippe is one of the oldest watch manufacturers in the world with an uninterrupted watchmaking history. Few international luxury brands carry the gravitas of their name, and for good reason. The firm's commitment to excellence in horological manufacture is unflinching, and their track record of innovation in design without peer. They continue to lead the industry, and even their fiercest competitors have nothing but the utmost respect for the company.

From the simple elegance of their Calatrava line to the stunning study in miniaturization that is reference 1518 perpetual calendar to the modern reference 5750P chiming watch, Patek’s catalog is chock full of some of the most elegant and complicated timepieces ever made. Family-owned and completely independent, the firm has the freedom to do what it wants — such as discontinue one of the world’s most beloved steel luxury sport watches, the reference 5711 — when it wants.

Owning a Patek Philippe is for many the ultimate goal of timepiece collecting, and for a certain type, the only timepieces they collect. Whichever way you look at it, there is no questioning the elegance of design, superlative manufacture of their cases and movements, or the sheer elegance and emotion that comes from owning one.

Of course for a brand that is steeped in heritage, we are told “You never actually own a Patek Philippe…”

Well, you know the rest.
