The reference 3974 was produced concurrently with the majestic Star Calibre in 1989 to celebrate Patek Philippe's 150th anniversary. The model is a minute repeater with perpetual calendar, 24 hour subsidiary dial and phases of the moon. At the heart of this sublimely complex creation is the R 27 Q calibre with 467 miniscule parts. It is among the most complicated wristwatch movements ever made. The innovation of the piece lies in its off-centred micro-rotor, the first such applied to the design of a repeater calibre. Thanks to the compact rotor design, the overall height of the highly complex movement is only 6.80 mm allowing the case to be incredibly thin.
The reference 3974 was mostly produced in yellow gold with very few examples in pink gold and is no longer in production. The first example of this reference is illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, p. 325.
