The Ref. 5524 Calatrava Pilot Travel Time with a second time zone and an analog date coupled to local time was launched in 2015 with a 42-mm white-gold case and a blue dial. It was followed in 2018 with a new interpretation in rose gold that was also available with a case diameter of 37.5 mm (Ref. 7234). Now, Patek Philippe is presenting this medium size for the original white-gold model as well. The legibility of the blue varnished aviator-style dial was optimized with applied numerals in white gold recessed and filled with luminous coating and luminous hands in blued white gold. The skeletonized white gold hour hand for home time is white lacquered.
The self-winding caliber 324 S C FUS stands out with its very easily operable Travel Time display of a second time zone. The actuation of one of the two pushers in the left-hand case flank moves the local time hour hand forward or backward in one-hour steps without affecting the precise rate of the watch. During the process, the skeletonized hour hand keeps indicating home time. Both time zones are linked with day/night indicators in apertures at 9 and 3 o’clock. As long as the owner of the watch remains at home, both hour hands are superposed and look like one hand. The two time-zone pushers are equipped with a patented safety lock that prevents unintended adjustments of the local time setting.
The new Ref. 7234G-001 is worn on a shiny navy blue calfskin strap secured with a white-gold clevis prong buckle. It is reminiscent of the harnesses that allowed pilots to keep their survival kits readily deployable in emergencies. The watch is delivered with a second calfskin strap in vintage brown. This new model complements the now pairable Ref. 5524G-001 with a diameter of 42mm. The two rose-gold watches, Ref. 5524R and Ref. 7234R, remain in the collection.
