As its name suggests—derived from the Calatrava Cross emblem, which combines four lilies as a symbol of the brand—the Calatrava has been Patek Philippe’s most iconic collection since its creation in 1932. This is the Calatrava Pilot Travel Time Chronograph. Introduced in 2023, it is the first flyback chronograph model in the series. The case measures 42 mm in diameter and features a rack khaki-green dial paired with a vintage-finished olive-green calfskin strap.It is powered by the automatic Caliber CH 28-520 C FUS movement, which combines three practical complications: a flyback chronograph with pushers at the 2 o’clock and 4 o’clock positions; a Travel Time function that displays two time zones via two central hour hands (one of which is a skeletonized hand indicating the departure time); and a local date displayed by a hand in the sub-dial at the 12 o’clock position.To maintain the case’s appearance, the two pushers for adjusting the local time—which are typically located at the 8 and 10 o’clock positions—have been replaced by a single large adjustment pusher in the same position, operated via an adjustment pin. This model stands out for its original and highly distinctive design.
