The Pioneer wristwatch dedicated to travel: The Patek Philippe Reference 2597 Travel-Time


At the dawn of commercial aviation, global elite travelers required an elegant tool to navigate a shrinking world, leading to the creation of the Patek Philippe Reference 2597 Travel-Time "Heures Sautantes" (Jumping Hours). Introduced in 1958 and granted a Swiss patent #340,191 in 1959 by Patek Philippe, this foundational masterpiece merged the mechanical genius of legendary independent master horologist Louis Cottier with Patek Philippe’s peerless aesthetic refinement, establishing the direct spiritual ancestor to all modern dual-time complications. Prior to its release, adjusting a timepiece for a new time zone required pulling the crown—a tedious process that halted the movement and disrupted timekeeping precision. Cottier’s ingenious, patented mechanism eliminated this vulnerability entirely by integrating two crisp, cylindrical pushers into the left flank of the case, empowering the traveler to advance or retreat the local hour hand in precise, one-hour increments while the minute and sub-seconds hands remained perfectly uninterrupted.


The historical importance of the Reference 2597 is flawlessly matched by its external architecture, which balances mechanical utility with sculptural elegance. The commanding 35mm case was crafted by the legendary Geneva casemaker Antoine Gerlach who bestowed the watch with dramatically elongated, faceted downturned lugs and a sharp silhouette designed to offset the asymmetry of the dual pushers.


Recognizing America's prominent role in developing the commercial aviation industry, Patek Philippe heavily targeted the growing North American market, poetically advertising the watch in the United States under the commercial names “Cross Country” and “Push-Button Time.” Retailing for an incredible $1,000 at the time, it was positioned as the ultimate luxury instrument for the mid-century transcontinental traveler, which explains why many of the finest surviving examples have emerged from prominent American estates.

Across its entire production history—encompassing both the two-hand First Series (1958–1961) and the three-hand Second Series (1962–1977)—it is estimated that Louis Cottier crafted a total off examples for this reference. Finding an early First Series example that retains its original, unaltered two-hand configuration, free from later factory upgrades, represents an occurrence of extraordinary rarity.


  • The First Series (1958–1964): This version relied on a two-hand setup where the single main hour hand could "jump" to a local time zone.


  • The Second Series (1962–1977): This generation added a secondary hour hand, an independently adjustable hour hand "often blued steel" to show the second time zone in sharp contrast.


The present first series timepiece offers the discerning connoisseur a rare opportunity to acquire a true milestone of horological history. Impeccably serviced by the brand and fiercely scarce, this Reference 2597 stands not merely as a timepiece, but as an enduring monument to the golden age of travel.
