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.
