Patek Philippe Annual Calendar Moonphase

In 1991, the soon-to-be graduates at the Geneva School of Engineering were presented with their final project prior to receiving their diploma — simplify the perpetual calendar.

Although the task was easier said than done, their work led to the inception of the annual calendar complication, patented by Patek Philippe in collaboration with the bright engineering minds at the GSE. Five years later, Patek debuted the Reference 5035 which marked the world’s first-ever annual calendar movement and finally bridged the gap between a triple date function and the formidable quantième perpétuel.

This example, a Reference 5036/1J, is housed in a 37mm 18k yellow gold case with a stepped polished bezel, sapphire crystal and signed crown. It features a satin silver dial with applied yellow gold Roman indices, recessed subsidiary registers indicating day and month, moonphase aperture and date window at 6 o'clock, and a luminous feuille handset.

Powered by Patek Philippe's Calibre 315 SQA 24H IRM LU self-winding movement, it comes fitted to a lovely solid yellow gold multi-link bracelet with a signed deployant clasp, giving the piece some added heft and presence on the wrist. This example has been treated to a professional case refinish and is stunning condition throughout, shipping with its inner and outer box set, purchase receipt and a Certificate of Origin dated October 2000.

Opulent, svelte and arguably the sexiest of Patek’s annual calendars, this timepiece is a stunner from the maison that invented the category!

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.
