Patek Philippe ref 3940P in platino full set , new old stock condition

The Patek Philippe Perpetual Calendar Ref. 3940P in platinum expresses a grand complication through remarkably restrained proportions. Its 36 mm case, gently curved lugs, and slim bezel frame a silvered dial with applied baton indexes and dauphine hands. Three compact subdials organize the perpetual calendar and moon phases without sacrificing the open space around the central hands. The understated appearance gives little indication of the complexity beneath the dial or the substantial feel of platinum. This example is presented in unworn, new old stock condition, accompanied by its full set of original box and papers.

Collector's Note

Introduced in 1985, the Ref. 3940 marked a decisive development in the modern Patek Philippe perpetual calendar. It replaced the Ref. 3450 with a flatter automatic movement and a balanced three-register display, establishing a design that remained in regular production until approximately 2007. The platinum version brings a different physical character to this familiar silhouette: visually discreet, yet noticeably substantial in the hand. Period 3940P examples were supplied with a solid caseback, rather than the exhibition backs found on many gold versions, preserving the quiet exterior of the watch.

Calibre 240 Q makes these proportions possible. Its recessed 22k gold micro-rotor winds the movement without adding the height of a conventional central rotor above the bridges. The calendar accounts for different month lengths and the four-year leap-year cycle, while the paired subsidiary indications keep the information compact and readable. Day and 24-hour information sit together at 9, balanced by the month and leap-year display at 3; the date and moon phases complete the composition below. In this example, unworn new old stock condition and the original full-set presentation complement the historical importance of the reference. The appeal is the preservation of a complete platinum perpetual calendar, rather than complexity displayed for its own sake.
