Launched in 2015, the reference 5524G Calatrava Pilot Travel Time brings 21st century innovation to Patek Phillipe’s 90-year tradition of aviation timekeeping. Pioneers of the skies, Phillipe van Horn Weems and Charles Lindbergh, inspired the brand’s original hour angle wristwatches, examples of which remain on display at the Patek Philippe Museum today. Patek’s infamous Travel Time mechanism was originally patented in 1959 and delivers astonishingly precise timekeeping across dual time zones. Newer features include the skeletal home-time hour hand, which can be hidden behind the local time zone hour hand for added visual simplicity. We love the 5524G for its nostalgic 1950s military feel, eminently legible Arabic numerals and bold 42mm case, which fuses classic Calatrava styling with today’s trend for oversized watches.
