At the heart of the new Longines Ultra-Chron is the calibre L836.6, a high-frequency "in house' movement. A watch is referred to as "high-frequency" when it is fitted with a movement whose balance-spring oscillates at 36.000 beats per hour (10 beats every second).

These movements, which Congines pioneered in 1914 (to time 1/10" of a second) and 1916 (to time 1/1000' of asecond), improved precise timekeeping. From 1959 onwards. Longines made use of the high-beat-movements to increase the accuracy of its watches. Thanks to a reduction of the disruptive effects of shocks or ot changes in the position of the movement. the high-beat movement proves to be more stable.

The new Longines Ultra-Chron will evoke an emotional response from any watch aficionado who is passionate about the iconic timepieces from one of watchmaking's most innovative eras. It will also win over new enthusiasts who will be thrilled to wear a bit of horological history on their wrists.

The History of high-frequency watches made by Longines

More than 100 of experience in manufacturing high-frequency timepieces has made Longines the leading expert on professional timekeeping and in sports watches The fast-beating movements are Of measuring 1/10th or 1/100!h Of a second. In addition, they have proven to extremely accurate. Over time. Longines has built a wide variety of high-beat stopwatches, chronographs and chronometers.

As early as 1914. Longines used high-frequency movements in its handheld stopwatches for the timekeeping of sporting events to measure 1110th of a second, Driven by the calibre 19,73N with a balance wheel oscillating at 36.000 beats hour. this chronograph proved very successful in sports. military and medicine. The pictured was equipped with a split-second hand, a modification that Longines introduced in 1922. TOimprove the reading Of 1/10th Of asecond. the chronograph hand rotates once around the dial in 30 seconds. The 15-minute counter is placed on the auxiliary dial near 120'clock.

In 1916. Longines was capable Of measuring 1/100th of a second, Based on the modified calibre 19.73N. the engineers in Saint-Imier enhanced the speed of the balance to a rate of 360.000 beats per hour - and thus enabled the exact reading of of a second. To achieve this. the chronograph hand flew over the dial in just three seconds to its starting position. The scale on the *riphery ot the dial was divided into very small steps of 11100th of a second. An instantaneous minute counter was placed at 12 and could measure up to three minutes.

As sporting events more important. Longines was appointed Official Timekeeper on numerous occasions. In 1938. it develogpd a larger and more accurate movement: the 24 lines. This chronograph was constructed on the basis of a navigational chronometer (cal. 24.99). The timer for ski races pictured here (from 1939) ticked at 36.000 hour to measure 1110th of asecond. The chronograph hand made one rotation in 30 seconds. which read the fractions Of a second. Equipped with a second split-second hand and a 30-rninute recorder. this professional stopwatch with three pushers was encased in Staybrite steeL The movement was adjusted to thræ pcsitions and gained special notice at the Observatory of Neuchåtel for its high accuracy. Longines built a variant of this calibre to measure 1/100th of a second.

To improve the 24-line calibre Of 193B, Longines launched a chronograph Of the same size in 1957 with a 30-minute counter and a system of stopping the balance. This professional instrument still had a minute and hour hand. but was also able to measure 1110th of a second thanks to its high -frequency movement (36.000 vibrations per hour). It was equipped with a flyback function and a hand. The from 1966 has a specicial chronograph hand With a so-called nonius-scale: at its extrernity there is a rack with nine "teeth" that indicate the end Ofthe hand. When the hand is stopped. one Ofthe -teeth' stops exactly in line with one of the "seconds" marks around the dial. The number at the base of this indicates the of tenths of a second.

In the 1950s. Longines was convinced that there was a need to increase the scientific efforts to maintain its competitive edge. Following the technical drawings of August 1958. Longines was ready to present the first high-frequency movement for a wristwatch in 1959; the calibre 360. oscillating at 36.000 beats hour. handmade and fine-tuned for Observatory Chronometer Competitions. This technical milestone was built in a series Of 200 pieces from 1959 to 1963. The rectangular movement improved the accuracy considerably, and it took first and second place in the accuracy competition at the Observatory of Neuchatel in 1961 and the following year. claimed first. second and third places. The daily deviation was around or 1/10th of a second.

1966: Ultra-Chron, the accurate high-beat wristwatch [CAL 431

In the 1960s. Longines' engineers worked on a mechanical mcwement that matched the accuracy of the new electronic watches. Thanks to their experience in timekeeping and in Observatory Chronometers. they knew that high-frequency watches were more consistent between the vertical and horizontal positions and suffered less drop in amplitude over a day, making them more accurate. The obstacles were lower wwer reserve and lubrication problems. Longines found the solution in the calibre 431 (with dry lubrication) and guaranteed an amazing accuracy of one minute a month, or two seconds a day. Being far more accurate than a chronometer by the COSC (Controle Officiel Suisse des Chronométres). the model was named Ultra-Chron. Longines registered the name in October 1966. The first Ultra-Chrons were sold in the United States in December 1966.

In 1967. Longines drew asporty version of the Ultra-Chrom adiver's watch with a bright-red minute hand. water-resistant to 200 metres. In early 1968. it was the first high-frequency diving watch. and probably the most accurate. driven by the unique calibre 431. As with all the Ultra-Chron models, Longines guarante«t an accuracy of one minute a month, which converts to two seconds a day. The tonneau- shaped watch was fitted with a calendar mechanism and a turning bezel, which enabled divers to determine their immersion times. To ensure legibility. even in murky water, the index marks on the dial hand. the triangle on the bezel and even the tip of the seconds hand (in the first series) were filled with tritium.

The timing of sports events with high-frequency instruments made by Longines

Thanks to its highly accurate and reliable timepieces Longines was requested to time the most important and prestigious sports events all over the world. Up to this day this honourable task has motivated Longines to improve the precision and accuracy of its watches and to develop ever better timing equipment.

Equestrian sports

As early as 1878. Longines had developed its first chronograph movement. which was scx)n fittæt in a case engraved with a jockey and his horse. These stopwatches were seen on the American racetracks in the 1880s. where they proved very among jockeys as well as the attending the races. In 1912. a new step was taken when Longines entered into its first official partnership with a show jumping event in Lisbon, Portugal. Throughout the years. Longines has timed thousands of To measure the closely-spaced competitors. the brand from Saint-Imier produced stopwatches with split-second hands as well as high-frequency movements accurate to 1/10th or 1/100th of a second. As a result of its legacy and expertise. Longines involvement in equestrian tcxiay includes show jumping, dressage. and flat racing disciplines.

Alpine skiing

Skiing down snowy mountains ranks among the most sports in Longines home country of Switzerland. In 1924. the brand timed the International Week of Winter Sports" in Chamonix (France). Some years later. the stopwatches from Saint-Imier were timing the World Ski Championships at the same place. In 1939. Longines presented a skiing timer with a high&at movement and split-second hand. measuring 1110th of a second.

For the Military Ski Championships in Crans-Montana (Switzerland) in 1945. Longines introduced a photocell light barrier on the finish line. In 1948. Longines was selected to time the legendary Kandahar downhill race in Sankt Anton (Austria). The organisers of the Ski World Championships of 1950 in (USA) chose Longines to be the Official Timekeeper. Today. Longines is the Official Partner and official of the FIS Alpine Ski World Cup tour and the FIS AlpineWorId Ski Championships and continues to time the most famous ski races in the FIS Alpine Ski World Cup. including. among many Others. the downhill races in Kitzbühel (Austria) or Lauberhorn-Wengen (Switzerland).

International Rallye-Sport

In January 1949. cars from all over Europe participated in the first edition of the Rallye Monte-Carlo after World War II. Timekeeping was entrusted to Longines. a status it held for more than years. In 1955. the brand from Saint-Imier launched a special punch printing device. Printogines. Equipped With a clock with an d-day power reserve. it allowed contestants to punch their own control card at each checkpoint over the more than km distance.

The reliable and robust device determined the Official winning times on the basis of the drivers' recorded passages through all checkpoints, It was so useful that it was appointed to time all the famous rallies of its - including the Coupe des the RAC Rally of Great Britain. the TAP Rally in Portugal. and the Thousand Lakes in Finland as well as the Rallye in Greece and the Rallye de Cute d'Ivoire in Africa.

Cycling races

In 1951. Longines was asked to time the world's leading cycling event. the Tour de France. The race across France was an excellent opportunity to test a new system that combined a camera at the finish line with a device recording each contestant's time on film. This timing system solvect the photo-finish problem when closely grouped reached the line at nearly the same time.

The former president of the French Cycling Federation. Jean Pitallier. personally timed every edition of the Tour de France from 1973 to 1980 with a pair of Longines high-frequency split-second stopwatches (ret, 7411). Longines was Official Timekeeper of the Tour de France until 1982 but its commitment to cycling went far beyond that; from 1954 until 1988. Longines timed the world track and road championships 28 times - as well as such renowned events as the Giro d'ltalia or the Vuelta in Spain.

Formula 1

In 1949 Longines introduced a timing system for motor races capable of recording 1110th of a second via a series of photos. It was so convincing that the International Automobile Federation certifi«i it in 1950. In the same year. the inaugural season of Formula I.

Longines timed the famous Grand Prix de Monaco and the Indianapolis 500 in the USA as well as Formula I races in Barcelona (Spain). Buenos Aires (Argentina). Spa (Belgium). Zandvoort (The Netherlands), and Bern (Switzerland) along with numerous other racing events in the following years. ay 1954, Longines had developect Chronotypogines. which used a sensor to automatically start and stop time. This system was soon adopted by the International Automobile Federation. In 1980, Longines launched (With Olivetti) a new method to time each car independently by using radio waves. This led to Longines" role as Official Timekeeper for all Formula 1 races from 1982 to 1992,
