Patek Philippe Perpetual Calendar

 What you’re looking at is arguably one of the most beautiful perpetual calendar watches ever made, full stop. And perhaps one of the most important, too. 

The reference 3940 was born in 1985, at a time when the watch world was in the midst of the Quartz Crisis and most brands were churning out inexpensive, battery-powered watches — and struggling to stay afloat. Alas, Patek Philippe was never one to follow the crowd, and released the ref. 3940 perpetual calendar with an in-house, micro-rotor-equipped automatic movement — a gauntlet drop if ever there was one. 

Made in several series and different metals, the watch we have here is in fact not a 3940. Housed in a 36mm white gold case, this piece is lugless, and set on a bracelet instead of a strap. Bearing the legendary reference 3945, it features a sapphire crystal, signed crown, a polished bezel, and one hell of a dial: Silver with white gold dauphine hands, it has a combination month/leap year indicator at 3 o’clock; a moon phase/date wheel at 6 o’clock; and a day/24-hour indicator at 9 o’clock. Simple, elegant and refined, it’s a design that was positively revolutionary in the 1980s, and still looks stunning today.

This 3945/1G is powered by the in-house Patek Philippe Calibre 240Q movement with micro rotor, and comes equipped with a beautiful Patek Philippe integrated 18K white gold bracelet with Patek locking clasp. 

Exquisite. 

If you’ve always appreciated the significance and beauty of the 3940, but desired something with a bit more character and flair (if that’s possible), look no further than the 3945, one of the rarest, and most beautiful references in Patek’s storied historical catalog. 

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.
