Patek Philippe extremely rare Perpetual calendar Ref:3448, circa 1968, in amazing condition. With its original certificate and box,
Reference 3448 is one of Patek Philippe’s best known perpetual calendar models and also one of the most easily recognizable thanks to its angular, architecturally designed case made by Antoine Gerlach. The model was introduced in 1962 and was at the time the first self-winding perpetual calendar wristwatch. It is thought that a total of only 586 examples were made, the majority in yellow gold cases. Few watches were cased in white gold and only two examples in platinum are known to date.
The movement is the celebrated caliber 27-460 that was upgraded and renamed caliber 27-460 Q with a perpetual calendar mechanism fitted on the movement plate underneath the dial. The caliber 27-460 Q is amongst the most sophisticated and lavish automatic movements ever made.
