Production of Ref. 3940 began in 1986 as the successor to Ref. 3448 and Ref. 3450. The present lot, made in 1987, belongs to the first series of this model. Production continued for over 20 years, with only some subtle changes made to the dial on later series. The design of the Ref. 3940 is such a classic that when it was replaced in 2007 with the Ref. 5140, the differences between the two models were nearly imperceptible. For an example of Ref. 5140, see lot 305.

An example of Ref. 3940 is illustrated in Huber, M. & Banbery, A., Patek Philippe Wristwatches, Second Edition, pp. 292-293.
