Patek Philippe Calatrava Pilot Travel Time, Ref. 7234G-001

Prestigious luxury Swiss watch manufacture Patek Philippe extends its family of Pilot-style watches by adding the new Ref. 7234G-001 Calatrava Pilot Travel Time model. Introduced in 2015, the Calatrava Pilot Travel Time family of watches takes inspiration from the manufacture’s aviator’s watches from the 1930s.

Patek Philippe Calatrava Pilot Travel Time, Ref. 7234G-001

In 2015, Patek Philippe launched Calatrava Pilot Travel Time (Ref. 5524G-001), the first pilot-style watch produced as a homage to the aviation pioneers. It boasts a highly unusual design as regards the prominent case as well as the dial with large white numerals and luminous hands that contrast crisply against the dark background. With its name and functional features, this modern pilot watch recalled the first aviator’s watches. Patek Philippe also took inspiration from two aviator’s watches that had been crafted in the manufacture in 1936 and are now exhibited at the Patek Philippe Museum in Geneva. They were very special siderometer (hour-angle) watches that allowed pilots to easily, precisely, and swiftly determine their current positions.

Instead of black, the usual dial color of aviator’s watches, a very special and elegant blue was chosen, offering an excellent contrast for optimized legibility. The siderometer architecture became obsolete with modern navigation aids, providing space for a function that is much more useful for modern-day travelers: the display of a second time zone made possible by the exclusive Travel Time mechanism. This easily operable system was patented by Patek Philippe in 1959 and 1996. It is characterized by two hour hands from the center. The local-time hour hand can be adjusted via two pushers in one-hour steps. The date is synchronized with local time.

This technical timepiece with a case diameter of 42mm laid the foundation for a new Patek Philippe family of timepieces with an eminently recognizable design. In 2018, Patek Philippe reinterpreted the original Calatrava Pilot Travel Time with a rose-gold version and a brown dial. In the same year, the manufacture launched the rose-gold model in the medium format (37.5 mm) that was destined for feminine wrists but also welcomed by men who prefer somewhat smaller watches.

In 2019, the pilot style took center stage again with the Ref. 5520 Alarm Travel Time grand complication. It combines the display of two time zones with a 24-hour alarm mechanism. The family also includes the two limited editions that were presented on the occasion of the Patek Philippe exhibitions in New York in 2017 (Ref. 5522A) and Singapore in 2019 (Ref. 7234A).

Following the success of this new watch collection, Patek Philippe has created the new mid-sized Ref. 7234G-001 Calatrava Pilot Travel Time in white gold. As a medium-sized version of the Ref. 5524G launched in 2015, the Ref. 7234G Calatrava Pilot Travel Time has a diameter of 37.5 mm to fit women’s and men’s wrists. The round Calatrava case in white gold is sleek with a flat and slightly beveled bezel as well as a caseband that merges almost seamlessly with the strap lugs.

The blue lacquered dial, inspired by aviator’s watches, is highly legible even in the dark thanks to applied white-gold numerals filled with a white luminous coating and broad luminous baton hands made of blued white gold.

The self-winding caliber 324 S C FUS movement consists of 294 parts and features the exceptionally convenient Travel Time system for displaying a second time zone. All it takes is the actuation of one of the two pushers in the left-hand case flank to move the luminous local-time hour hand clockwise (with the lower pusher) or counter-clockwise (upper pusher) in one-hour increments. During such adjustments, the local time hand is disconnected from the movement, so the accuracy of time displayed by the minute and seconds hands is not compromised. The skeletonized hour hand continues to indicate home time.

Patek Philippe Calatrava Pilot Travel Time, Ref. 7234G-001

Both time zones have separate day/night indicators (LOCAL window at 9 o’clock for local time, HOME window at 3 o’clock for home time) to simplify time setting on the go and to prevent unintentionally waking up loved ones with a phone call in the middle of the night. As long as the watch owner is at home, the two hour hands are superposed.

The two time-zone pushers are equipped with a patented safety system that prevents unintended adjustments of the local time setting. Before they can be actuated, they must be unlocked with a quarter turn, which is simplified by delicate fluting. Afterwards, they must be locked again with a quarter turn in the opposite direction.

The analog date at 6 o’clock shows the date in three-day increments to improve legibility without cluttering the scale. A useful feature for travelers is that the date is always synchronized with local time because the time-zone pushers also increment or decrement the date if the local time hour hand passes midnight either clockwise or counter-clockwise.

The new Ref. 7234G is worn on a shiny navy-blue calfskin strap secured with a clevis prong buckle in white gold. It is reminiscent of the harnesses that allowed pilots to keep their parachutes and survival kits readily deployable. The package also includes a second calfskin strap in vintage brown with contrast stitching much like the belts for classic pilot overalls.

Ref. 5522 Calatrava Pilot New York 2017 Special Edition

This watch with hours, minutes, and seconds was launched in a limited edition of 600 pieces on the occasion of Patek Philippe’s “The Art of Watches Grand Exhibition New York 2017”. As a special feature, its 42-mm case is made of stainless steel, a rare case material for watches outside of the manufacture’s casual sports collections. The inimitable blue color of the dial recalls the livery of American fighter planes in the 1930s. The self-winding caliber 324 S movement can be admired through the sapphire-crystal back decorated with the engraving “PATEK PHILIPPE NEW YORK 2017”.

Ref. 7234A-001 Calatrava Pilot Travel Time Singapore 2019 Special Edition

As a travel companion par excellence for globetrotters (launched in 2019), this self-winding grand complication features the exclusive Travel Time time-zone system with a 24-hour alarm mechanism that strikes a classic gong with a hammer and digitally displays the alarm time. To achieve this, the manufacture created a totally new integrated movement with 574 parts. Four patent applications were filed for the alarm mechanism. The functional logic has been carefully thought through to simplify the operation of the watch as much as possible. Various safety and isolating mechanisms prevent damage to the movement as a result of incorrect manipulation.
