The story · Since 1936

The story of the Patek Philippe Calatrava Pilot Travel Time

In 2015 Patek Philippe unveiled a 42 mm white gold pilot's watch with large numerals and luminous hands, and critics said it did not look like a Patek. Its roots were two 1936 hour-angle watches built for aerial navigation, and ten years later the family it started counts travel times, an alarm and a flyback chronograph.

Chapters

  1. 1936

    Hour-angle watches for navigators

    Patek Philippe made oversized hour-angle wristwatches in 1936, meant to be worn outside the pilot's suit as navigation instruments. Two 1930s hour-angle watches are shown at the Patek Philippe Museum in Geneva; Christie's describes a unique split-seconds prototype, 55.3 mm across, as one of the two Patek Philippe examples.

  2. 2015

    A surprise at Baselworld

    Patek Philippe presented the Ref. 5524G Calatrava Pilot Travel Time at Baselworld 2015: 42 mm of white gold, a blue lacquered dial, luminous Arabic numerals and its patented Travel Time second time zone. The press called it unexpected and critics said it did not look like a Patek Philippe, while Thierry Stern, who succeeded his father in 2009, wanted a fully functional watch for the modern man.

  3. 2017 to 2019

    A family takes shape

    A steel three-hand Ref. 5522A followed for the 2017 New York exhibition, then in 2018 a rose gold 5524R with a brown dial and a 37.5 mm 7234R for smaller wrists. In 2019 came the 5520P Alarm Travel Time and a steel 7234A for the Singapore exhibition.

  4. 2020 to 2023

    Smaller gold, then a chronograph

    In 2020 the white gold model gained a 37.5 mm sister, the Ref. 7234G. In 2023 the line married the Travel Time system to a self-winding flyback chronograph in the 42 mm white gold Ref. 5924G.

  5. 2025

    Ten years and an ivory dial

    For the tenth anniversary Patek Philippe replaced the blue-dial 5524G with the 5524G-010, keeping the 42 mm white gold case but switching to an ivory lacquered dial and a khaki composite strap. The Business Times describes the original 5524G as the first model built from scratch under Thierry Stern's watch.

FAQ

What lug width does the Patek Philippe Calatrava Pilot Travel Time use?

Patek Philippe Calatrava Pilot Travel Time references use 18 mm or 20 mm or 21 mm depending on the reference and case size, so check yours in the list below. The most common is 21 mm (3 of 7 references with a known width). These widths come from our database and are not yet verified.

Do all Patek Philippe Calatrava Pilot Travel Time references take the same strap?

No. 3 different lug widths appear across the line, often by case size or generation. Check the reference engraved on the case back or between the lugs.

Which sizes exist?

Two: the original 42 mm (5524, also used by the 5522A) and the 37.5 mm mid-size (7234). Both 42 mm and 37.5 mm cases measure 10.78 mm thick according to Swisswatches Magazine.

What strap and buckle come with it?

Calfskin straps on most models (brown on the 5524G-001, vintage brown on the rose gold models, navy or brown on the 7234G) with a clevis prong buckle; the 2025 5524G-010 comes on a khaki green composite strap. Monochrome links the clevis buckle to the harnesses aviators used for their emergency kit.

Will the time-zone pushers move by accident when I change the strap?

The pushers at 8 and 10 o'clock that jump the local hour are screw-down: they must be unlocked with a turn before they can be pressed, which guards against accidental changes.

Help

What is lug width?

The gap between the two lugs that hold the strap, in millimetres. A new strap must match it exactly: 20 mm lugs take a 20 mm strap.

Measure it in 30 seconds

  1. Take the strap off, or look at the back of it: many straps print their width.
  2. Measure the inside gap between the lugs with a caliper or a millimetre ruler.
  3. Round to the nearest whole millimetre. Most watches use 18, 20 or 22 mm.

Strap, quick release or system?

Most watches use spring bars, so any strap of the right width fits. Many smartwatches use their own band system instead, such as Apple Watch bands or Garmin QuickFit.
