The 1950s and 1960s were the Golden Age of jet flight, with travel times around the globe reduced from days to hours, and for the international jet-set, airplanes became the preferred mode of travel. The immediacy of air travel created a need for pilots and travelers to tell time both locally and at home. Patek Philippe patented Louis Cottier's “Time Zone Watch” system in 1959. The calibre 12’’’400 HS (heures sautantes or jumping hours) was an elegant and ingenious design, which helped the firm create an iconic mid-century wristwatch that demonstrated the exuberance of the new modern era.

Reference 2597 was made in two versions; first generation models, such as the present lot, features an independently adjustable hour hand. The pushers on the left side of the case are used for advancing or setting back the hour hand in one-hour increments. The second version, launched in 1962, featured an additional hour hand.

The present reference 2597 stands out for its original overall condition. The large case has strong proportions with downturned lugs, slight oxidation around the case pushers with a pleasing rainbow colored patina, indicative that the watch has hardly seen any wear in recent years. The dial is nicely aged, with the raised, hard enamel print fully intact throughout. The dial features the prestigious retailer signature, Tiffany & Co., making it one of only a few known 2597 models with such a coveted signature. Consistent with other wristwatches sold by the retailer during this era, the top left lug has a hand-etched number, most probably Tiffany’s internal inventory number. Furthermore, the movement is accordingly stamped ‘HOX’ the correct import mark for the American market. This masterpiece of understated 1950s design and watchmaking is the perfect travel watch for the discerning collector.
