The history of Travel Time watches from Patek Philippe traces back to the mid-20th century when the brand recognized the growing demand for timepieces that could accommodate the needs of international travellers. In response to this, Patek Philippe developed a mechanism that allowed wearers to easily track two time zones, thus creating a new category of watches known as "Travel Time" or "Dual Time" watches.
Patek Philippe introduced its first Travel Time watch, the reference 2597, in 1959 after Louis Cottier's 1953 prototype. It featured a distinctive dual time zone display with an additional hour hand, enabling travellers to keep track of their home time and local time simultaneously.
Over the years, Patek Philippe continued to refine and enhance their Travel Time watches, incorporating new complications and design elements. In 1997, the manufacture introduced the reference 5034, with the ultra-thin manual winding caliber 215 movement, allowing a slimmer case profile.
In 2001, Patek Philippe unveiled the reference 5134, offering a more modern take on the case and dial execution for daily use, this 37mm Travel Time was in production until 2008.
