Patek Philippe Annual Calendar Regulator

 The annual calendar is a complication invented by Patek Philippe.

While it plays second fiddle to the perpetual calendar in the minds of most collectors, the reality is that the construction of this calendar mechanism is by no means a simple feat, and requires impressive micro-engineering and design acumen to execute well. Able to account for months of different lengths, it only requires manual adjustment once per year — at the end of February. 

This particular annual calendar is one of the best calendar designs to emerge from Patek in the past decade. A Reference 5235G-001, it’s housed in a 40.5mm 18K white gold case with a sapphire crystal, a signed crown, and a polished bezel. It features a beautiful, vertically brushed ‘regulator’-stype dial with stamped blue ‘Arabic’ indices, a silvered ‘railroad’ minute track, a matching, blue ‘stick’ handset throughout, and day, date, and month displays.

Powered by the impressive Patek Philippe Calibre 31-260 REG QA automatic micro-rotor movement and paired to a signed, blue alligator leather strap with an 18K white gold, signed pin buckle, this stunning calendar watch is proof of Patek’s continued mastery of complicated watchmaking. 

Strap this elegant timepiece on your wrist for an instant appreciation of haute horlogerie!

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.
