Overview

The Patek Philippe 5140G-001 is a 37.2 mm white-gold perpetual calendar from the Grand Complications collection, produced between 2006 and 2017. Its silvery opaline dial arranges the day, date, month, leap-year indicator, and moonphase across three subdials in the brand's classic symmetrical layout. Powering the watch is Calibre 240 Q, a micro-rotor automatic movement celebrated for its exceptionally low profile.

History

Reference 5140 succeeded the long-running 3940 as Patek Philippe's principal round perpetual calendar, retaining the three-subdial architecture while moving to the thinner Calibre 240 Q. The white-gold 5140G-001 variant was offered throughout the reference's production life, appealing to collectors who favoured the cooler, more formal character of white gold over yellow or rose. When the 5140 was retired around 2017, it was succeeded by the larger 5320G, cementing the 5140's reputation as a refined, restrained chapter in the perpetual-calendar lineage.

Notable points

Case diameter of 37.2 mm places the 5140 at a gentlemanly, pre-inflation size that many collectors regard as ideal for a dress perpetual calendar.
Calibre 240 Q is built on Patek Philippe's ultra-thin 240 base, using a peripheral micro-rotor in 22k gold to keep the movement's overall height remarkably low.
The silvery opaline dial employs applied gold hour markers and a three-subdial layout — day at 9 o'clock, moonphase and date at 6 o'clock, and month with leap-year at 3 o'clock.
All calendar indications are mechanically programmed to account for months of unequal length and leap years, requiring no manual correction until 2100.
The 5140 was produced for roughly eleven years before being discontinued, giving it a well-defined production window that aids collector identification.
