Pre-Owned Patek Philippe Patek Philippe Annual Calendar

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 iteration of the Patek Philippe Complications Annual Calendar. Designated as a Reference 5250G-001, this impressive timepiece features a 40mm white gold case with sculpted, contoured lugs, a concave bezel, and a polished finish.

Its non-luminous sectored dial features two-tone gray and silver finishing with black applied indices. The dial presents with a set of day-date-month apertures at 12 o’clock, and a subsidiary pointer-date dial complete with a moonphase indicator at 6 o'clock.

The reverse features an exhibition back providing a window through which you can admire the self-winding Caliber 324 S QA LU with 21k gold winding rotor. This handsome piece comes fitted to a signed black alligator strap with an 18k white gold signed pin buckle and is also accompanied by its inner and outer boxes, books, leather folio and Certificate of Origin dated 04/2013.

This piece packs pedigree, refinement, function and outstanding craftsmanship that can only be expected on Patek Philippe.

Any old wristwatch can tell the time. Few truly define it.
