With its new Ref. 5524 Calatrava Pilot Travel Time, Patek Philippe pays tribute to the courageous pioneers of aeronautics, recalls milestones in aviation, and touches upon the fact that the eminent family-owned Genevan manufacture also contributed to the conquest of the skies.
Patek Philippe's Ref. 5524 Calatrava Pilot Travel Time is a decidedly masculine watch that aptly symbolizes the conquest of the skies by aircraft and the conquest of the wrist by wristwatches. Rather than being a nostalgic reminiscence of the hour-angle watch that became obsolete with the advent of GPS navigation, it is a precise and dependable timekeeping instrument with a time-zone function that is especially useful in air travel.
In keeping with "Tradition and Innovation", the philosophy of the manufacture which just turned 175, Patek Philippe refined the two-time-zone mechanism – it was awarded a further patent in 1996 – to a new level of perfection. When the local-time hour hand is moved forward or backward in one-hour increments with the two pushers in the case, an isolator uncouples the time-zone mechanism from the going train. This prevents the degradation of the amplitude of the balance and allows it to continue oscillating at a regular rate. The advantage: the watch continues to run with the accustomed accuracy.
The special properties of this material, combined with the geometry patented by Patek Philippe, assure high dependability as well as the rate accuracy tolerance of -3/+2 seconds per day as specified by the Patek Philippe Seal. The sapphire-crystal display back reveals beautiful details such as the chamfered bridges with Geneva striping, the circular-grained gold rotor with perlage in the center, snailed flanks, and a Calatrava cross. It features magnificent contrasts with bright shimmering metal, gold-filled engravings, and sparkling red bearing jewels.
The sleek classic face of the Calatrava Pilot Travel Time is framed by a large-format 42-millimeter white-gold Calatrava-style case. Its bezel is flat and slightly inclined; the caseband merges elegantly with the lugs that secure the strap bars. The crown and the two time-zone pushers at 8 (+1h) and 10 o'clock (-1h) are fluted for a slip-free grip and add a technical look that suits the design of a precise measuring instrument.
