Together with an Extract from the Archives confirming sale on February 3rd, 1961.

Production of Ref. 2597 HS (Heures Sautantes) began in 1958 after Louis Cottier's 1953 prototype and Patek Philippe patented the model in 1959. With specially designed pushers to the left case side, the wearer is able to advance and retard the hour hand in one hour increments, thereby easily adjusting the watch for different time zones.

The first version of the wristwatch was made with a single hour hand, such as the present lot. It is estimated that approximately one hundred examples of this model were ever created, in yellow and pink gold, and with two and three hands. Watches similar to the present example, in yellow gold and featuring two hands, made up perhaps just over half of the complete production run.

Offered on behalf of a descendant of the original owner, the present example boasts exceptional condition. Over the past twenty-five years, the watch has been tucked away in a safety deposit box and is today being offered for the first time at auction.

A similar example is illustrated in Huber, M. & Banbery, A., Patek Philippe Watches, First Edition, p. 184.
