Patek Philippe Calatrava Pilot Travel Time

In 1884, the International Meridian Conference in Washington, D.C. established the system of standard time and the division of the globe into 24 time zones. And ever since, Patek Philippe’s engineers and watchmakers have been using their ingenuity to produce watches with multiple time zones that are both highly legible and easy to use.
 
1884年，在華盛頓舉行的國際子午線會議規定了全球標准的時間系統，並將全球劃分為24個時區。自此，百達翡麗的工程師和制表師便一直運用自己的聰明才智，思索如何創造出可在不同時區之間切換的時間顯示功能，而且必須便捷可靠。
