Patek Philippe has launched the self-winding white-gold Calatrava Pilot Travel Time in the new medium format (37.5 mm) that assures a subtle presence on the wrist. The legibility of the blue aviator-style dial was optimized with luminous applied numerals in white gold and baton-style luminous hands in blued white gold with luminescent coating. Its exclusive dual-time-zone system stands out with extreme user-friendliness. The date display is coupled with local time.
