Description

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 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 piece transports us forward to the present day and is a handsome modern interpretation of the Patek Philippe Complications Annual Calendar. Designated as a Reference 5205G-001, this lovely timepiece features a 40mm 18k white gold case with sculpted, hollowed lugs, a concave bezel, and polished finish.

The silver, two-tone sector dial features a set of applied white gold indices and presents a set of day-date-month apertures at 12 o’clock, a subsidiary pointer-date dial with a moon phase display and a ‘dauphine’ handset. 

The back side features an exhibition back providing a window to admire the self-winding Caliber 324 S QA LU and its 21k gold winding rotor adorned with the hallmark Patek Philippe sealIt comes fitted to a signed black alligator strap with a matching 18k white gold signed pin buckle. This piece is also accompanied by its box set, leather folio, books, corrector tool, and Certificate of Origin dated 04/2011.

There’s no doubt the Nautilus and Aquanaut have gotten their time in the sun, and even vintage Patek Philippe in general continues to demand the attention of any savvy collector. But let us not pass over the high-complication heavy-hitters hiding in plain sight in Patek’s modern catalog!
