The reference 2597 "travel time" was launched in 1958 as a response to the arrival of transatlantic flights in the 1950's, and the need for a watch to quickly switch from home time to local time. Louis Cottier developed a solution for Patek Philippe that used two correction buttons in the band to adjust the position of the hour hand in either direction by exactly one hour while maintaining the correct relationship to the minute hand.
Reference 2597 was produced in two versions, the first featuring an independently adjustable hour hand, like the present watch. The second version included an additional hour hand. The model did not enjoy much commercial success, and production did not continue for long. Nevertheless, Cottier's patented wheel train is today the basis for Patek Philippe's Travel Time reference 5034, launched in 1997.
Examples of both versions of reference 2597 are illustrated in Patek Philippe Wristwatches by Martin Huber and Alan Banbery, second edition, p. 238 & 239.
