Before I knew anything about watches, I knew about the people who wore them. Not celebrities. Actual pilots. People whose idea of a bad day involved ice storms over the Atlantic or trying to land in the dark with nothing but fuel fumes and a wristwatch.
This isn't about one watch. It's about Longines - and how it ended up on the wrists and in the cockpits of the people who mapped the world by air and sea. Not because of sponsorships or marketing budgets, but because their lives depended on something that worked.
In the early 20th century, Longines wasn't just making watches. It was making navigation instruments that happened to fit on your wrist. Chronometers, rotating bezels, center dials - tools built for calculation, not compliments. Before radar and GPS, precision timekeeping was survival.
Every name that follows wore Longines not for status, but for necessity.
Beginnings in Saint-Imier
Longines was born in a valley. In 1832, Auguste Agassiz began producing pocket watches in Saint-Imier, Switzerland - a place with no electricity, no rail, and not much reason to expect global success. But Agassiz and his nephew Ernest Francillon were early visionaries. Francillon saw industrialization as the future and built a factory on the "long meadows" (les longines) that would give the brand its name. From the start, every watch bore the winged hourglass and a serial number to fight counterfeits - a symbol that still endures.
That foundation of precision would take Longines from a remote valley to the world's poles, mountains, oceans, and skies.
North to the Edge of the Map
In the late 19th century, explorers carried Longines not on their wrists but in their ships. Italian nobleman Louis-Amedee de Savoie, Duke of Abruzzi, brought six Longines pocket chronometers set to -20 C when he sailed toward the North Pole in 1899. His team used them daily to calculate position on the shifting ice until wind and starvation forced them back. They reached 86 degrees 34 minutes north - a record for the time.
Five years later, in 1904, Canadian captain Joseph-Elzear Bernier led a 429-day Arctic expedition using two Longines Express Monarch chronometers to calculate Greenwich time. After months of cold and magnetic interference, one was off by 13 seconds and the other by just 4 - remarkable accuracy for the age. Bernier's loyalty to Longines lasted his entire career.
These were the days when being "off" by a few seconds could mean missing land entirely.
Pioneers in Flight
By the 1920s and 1930s, the age of exploration had moved skyward, and Longines went with it.
Charles Lindbergh
In May 1927, Charles Lindbergh's Spirit of St. Louis lifted off from New York for Paris, loaded with fuel but no radio. He navigated by compass and watch, trusting Longines - the official timekeeper of the Federation Aeronautique Internationale - to record his 33-hour, 3,600-mile flight. When he later collaborated with U.S. Navy instructor Philip Van Horn Weems, Lindbergh helped design a new watch to calculate longitude using celestial navigation. Longines produced it in 1931: the Hour Angle Watch, with rotating bezel and inner disc calibrated for degrees and arcminutes.
It wasn't jewelry; it was a mechanical sextant for the wrist.
Amelia Earhart
Five years after Lindbergh's flight, Amelia Earhart became the first woman to fly solo nonstop across the Atlantic. On May 20, 1932, she took off in freezing winds and landed in Northern Ireland 14 hours and 56 minutes later, wearing a Longines chronograph. She had used the same watch on her first transatlantic crossing as a passenger in 1928. The caseback engraving later read: "This watch was worn by Amelia Earhart on her two transatlantic flights." For her, timekeeping was navigation, not ornament.
Elinor Smith
At 18, Elinor Smith was already a phenomenon. She flew under all four bridges in New York after a dare, then set endurance and altitude records. In 1930 she reached 27,418 ft - higher than anyone else had flown - and wrote to Longines afterward: "Happy to advise you of new altitude record just accomplished again exclusively with Longines watches. Watches functioned perfectly at all times." It wasn't a press release; it was gratitude from someone who nearly blacked out at 26,000 ft and lived to tell it.
Ruth Nichols
At a time when there were fewer than a dozen licensed female pilots in America, Ruth Nichols became the only woman to hold world records for speed, altitude, and distance - 210 mph, 28,743 ft, and 1,977 miles. She wore a Longines during all her major flights, including her 1931 altitude record when the engine failed and two cylinders blew out in subzero cold.
Amy Johnson
Britain's Amy Johnson made history in 1930 as the first woman to fly solo from England to Australia - 11,000 miles in 19 days. She broke record after record, including a London-Cape Town flight that beat her husband's time by over ten hours, timed by her Longines. Later, as a Royal Air Force officer during World War II, she died ferrying aircraft in poor weather - still wearing her pilot's watch.
Across Oceans and Continents
Longines timepieces weren't just for individual feats but for collective leaps of faith.
Dieudonne Costes and Joseph Le Brix
In 1927, French pilots Dieudonne Costes and Joseph Le Brix completed a 35,652-mile flight around the world with a Longines chronometer on board. It was the first aerial circumnavigation with a single aircraft, including the first nonstop crossing of the South Atlantic from Senegal to Brazil.
Dieudonne Costes and Maurice Bellonte
Two years later, Costes teamed up with Maurice Bellonte for the first Paris-to-New York flight - the hard way, against headwinds. Their Breguet XIX biplane Point d'Interrogation carried two Longines sidereal clocks built for 24-hour dials and an eight-day power reserve. They landed in New York after 37 hours, proving Europe and America could truly connect by air.
Paul Codos and Maurice Rossi
In 1933, Paul Codos and Maurice Rossi pushed the limits of endurance again, flying nonstop 5,657 miles from New York to Lebanon - 55 hours in the air, their Bleriot 110 powered by a Hispano-Suiza engine and guided by Longines chronometers.
Clyde Pangborn and Hugh Herndon
Two years earlier, in 1931, Americans Clyde Pangborn and Hugh Herndon became the first to fly nonstop across the Pacific. To save weight, they threw out the landing gear mid-air and flew barefoot. After 41 hours and 13 minutes, they belly-landed in Washington state, guided by Longines cockpit clocks that "kept absolutely accurate time even as the water in our canteens froze," as Herndon wrote afterward.
The Age of Airships and Adventure
Not all aviation pioneers flew airplanes.
Hans von Schiller, captain of the Graf Zeppelin, navigated its 1929 round-the-world voyage with Longines chronometers in the cockpit. He later commanded the Hindenburg, whose bridge carried three Longines clocks measuring legal, Greenwich, and sidereal time. Schiller missed the zeppelin's final flight by chance, surviving the 1937 disaster that claimed his crew.
Swiss aviator Walter Mittelholzer used Longines instruments during his photographic expeditions from Zurich to Iran and later to Cape Town in the 1920s. He was the first to fly over Mount Kilimanjaro, capturing images that introduced much of the world to Africa from above.
Wiley Post, an Oklahoma oilman turned pilot, wore a Longines on his record-setting circumnavigation in 1931 with navigator Harold Gatty - 15,474 miles in eight and a half days. He later flew solo around the world in 1933, developed the first functional pressure suit, and discovered the jet stream.
And in July 1938, Howard Hughes shattered the around-the-world record in his Lockheed Super Electra, completing the journey in 3 days, 19 hours, and 14 minutes. The telegram sent from Paris read: "Aircraft of Howard Hughes equipped exclusively with aviation chronometers and chronographs by Longines." His plane carried the Longines Siderograph, a sidereal time instrument for navigating by stars long before satellites.
The Polar Connection
The brand's link to exploration extended back to the poles. U.S. Admiral Richard Byrd, wearing Longines instruments, became the first to fly over the South Pole in 1929 - an 18-hour flight using a sun compass and wrist chronometers to guide the way. He later praised the watches for their "most satisfactory service" in the Antarctic cold.
French explorer Paul-Emile Victor, decades later, relied on Longines deck chronometers during his Arctic expeditions. In temperatures as low as -40 C, they kept perfect time when most machines froze. "They were the difference between failure and success," Victor wrote after crossing Greenland's ice desert in 1936.
And when Swiss physicist Auguste Piccard and his son Jacques descended into the Mariana Trench in 1960, Longines stopwatches timed the dropping of the iron ballast that allowed their bathyscaphe to resurface. Those same instruments had already accompanied them in 1953 to a record depth of 3,150 meters.
From Arctic ice to oceanic pressure, the same brand measured both extremes of human endurance.
Tools That Changed Time
Behind all these stories was constant invention. Longines wasn't just a passenger on history; it was building it.
- 1913: The first wrist chronograph with column-wheel movement (cal. 13.33Z), accurate to one-fifth of a second.
- 1929: The Weems Second-Setting Watch, patented to synchronize precisely with radio time signals - the first rotating-bezel wristwatch.
- 1931: The Lindbergh Hour Angle Watch, blending celestial navigation with wrist portability.
- 1935: The world's first flyback chronograph, allowing pilots to reset and restart timing instantly.
- 1942: The central-minute-counter chronograph, simplifying elapsed-time reading in flight.
Each of these innovations began as a practical response to real problems. Precision wasn't aesthetic; it was existential.
Final Thoughts
No one reading this has flown across the Atlantic with nothing but a compass and a watch. But the idea still resonates. A tool you trust. A device you check in moments of doubt. Something that works when everything else might not.
You don't have to be in the stratosphere to want that. This isn't nostalgia; it's respect for engineering that earned its reputation by helping people come back alive.
We talk a lot about heritage in watch circles, but real heritage isn't a marketing word. It's written in the logs of explorers who used Longines chronometers to find their way home, in letters from pilots who thanked the factory in Saint-Imier because their seconds stayed true.
The watch was never the star of those stories. It was a silent co-pilot. And that's the role it played best.
