The Patek Philippe reference 3940 stands out as one of Patek Philippe's most iconic models ever created. Introduced in 1985 under the guidance of Philippe Stern, it represented a notable departure in design for the brand's classical perpetual calendar models. During its production period, it ranked among Patek Philippe's longest-running references, with production halting around 2007.

The sleek, stepped and finely designed 36mm diameter Calatrava case infuses the watch with a distinct contemporary elegance, while the calendar functions on the dial are communicated through subdials rather than apertures. Fuelled by the groundbreaking ultra-thin caliber 240, which introduced Patek Philippe's inaugural use of a micro-rotor, it facilitated the creation of an elegant and remarkably slim case that hugged the wrist snugly.

The present reference 3940 in 18k white gold however, sits in a league of its own. The 2015 Patek Philippe Watch Art Grand Exhibition held the distinction of being the largest overseas exhibition ever hosted by Patek Philippe at that time. To commemorate the brand’s 175th anniversary and this significant event, Patek Philippe unveiled, for the first time publicly, a collection of previously discontinued models adorned with special dials. These exclusive watches were exclusively offered to Patek Philippe's most esteemed and privileged clientele. Today, timepieces from this historic exhibition are revered as prized possessions due to their scarcity and pivotal role in Patek Philippe's illustrious history.

Fresh to the auction market, the present timepiece is part of only a handful of reference 3940s specially made for the 2015 Patek Philippe Watch Art Grand Exhibition. Showcasing a captivating salmon dial and open caseback, Patek Philippe used new old stock cases, paired with different dial colours that had never appeared before in the reference, but using the dial layout of the 5140, as can be seen from the present example.

Immensely captivating, the present Saatchi Edition reference 3940 is furthermore accompanied by its original and full set of accessories including the certificate of origin, setting pin, additional numbered caseback and winding presentation box.
