Patek Philippe Ref.5140, white gold perpetual calendar wristwatch with moonphase. Cal. 240 Q, 27 jewels, 37mm. Accompanied by a box, leather wallet, setting pin, spare case back, product literature and Certificate of Origin. 

Patek Philippe has a long and rich history in perpetual calendar timepieces and reference 5140G is an heir to one of Patek Philippe's most iconic modern perpetual calendars: reference 3940 launched in 1986 and in production for 20 years.

Reference 5140 beats to the rhythm of Patek Philippe's ultra-thin caliber 240Q. Its 275 components add up to a thickness of merely 3.88 mm thick. The sapphire crystal caseback enables a full view into the beautiful hand decoration of the movement, and the ability to admire its freely spinning 22K micro-rotor.
