Accompanied by an Extract from the Patek Philippe Archives confirming the date of manufacture as 1976 and its subsequent sale on November 16th of the same year.
According to our research the present watch has never before appeared at auction.
Patek Philippe produced the extremely popular reference 2499 from 1950 to 1985 in 349 examples. Throughout this reference's history the features of the dial and case underwent four transformations. The first series featured a tachometer dial with square buttons whereas the second series also featured a tachometer scale but possessed round buttons. The third series, as with the present watch, maintained the round buttons but the dial appears without the tachometer scale. The fourth and final manifestation was nearly identical to the third series solely with the addition of a sapphire crystal.
The third series of the reference 2499 was made between 1960 and 1978. For an example of a reference 2499 see Huber & Banbery, Patek Philippe Wristwatches, p. 302, pl. 458.
