This stunning Patek Philippe Annual Calendar reference 5146P was first introduced in 2005 and succeeded the smaller 5035 that was introduced in 1996. This reference features a 39mm case diameter with exhibition case back and houses a self-winding calibre 324 S IRM QA LU, which indicates the day, month and power reserve, while the date and moon phase are displayed through apertures. This example, made in platinum, features a grey sunburst dial with contrasting white font and minute track with white-gold hour markers. It is complimented by its original dark blue Patek Philippe crocodile strap and platinum deployment clasp.

The watch remains in excellent original condition. The case has some light scratches from occasional use. The service history is unknown however we have tested the watch and it is keeping excellent time. In addition to this, the watch is fully functioning and therefore not in need of an immediate service.

The reference 5146P boasts moonphase calendar & power reserve complications whilst still retaining a classic and understated look that we’ve come to expect from a Patek Philippe.

Founded in 1839 by Antoine Norbert de Patek and François Czapek, Patek Philippe began life as Patek, Czapek & Cie, whereby it existed until 1845 until it was broken up as a result of a disagreement between the two founders. Joined by French watchmaker Adrien Philippe, Antoine Patek renamed the company Patek & Cie on May 15th, 1845. Under its new leadership, Patek Philippe continued to evolve as a watchmaker, offering some of the finest timepieces the world had seen. With royal customers like Queen Victoria and Countess Koscowicz of Hungary in the mid-1800s, Patek Philippe’s products had found their way to the perfect audience. From there, Patek Philippe continued to evolve well into the 20th century (even following a company restructuring) and become known as the apex of Swiss watchmaking.

Today, Patek Philippe’s reputation precedes them as they are well-established as one of the best watchmakers on Earth, in more ways than one. While some brands specialise in particular complications, designs and uses, Patek Philippe found their niche in supplying a broad range of watches that were, to be frank, better than everyone else’s. Continuing that very same vein, Patek today is one of the brands that continue to outperform others in desirability, brand equity and watchmaking prowess.

In 1993, Patek Philippe was taken under the control of Philippe Stern as President of the company. Under his vision Patek has continued with their traditional approach to watchmaking, remaining undeterred by market trends, the desires of the masses and the appeal of quick short-term revenue generation. Alongside arising competition from brands like Lange & Söhne and under Philippe Stern’s direction, Patek began to vertically integrate their manufacturing processes to ensure the quality of its timepieces. A significant move at the time, this eradicated Patek’s reliance on third-party suppliers and allowed them to remain ahead of the curve as far as what their competition was doing.
