Zenith SA is one of the oldest continuously operating Swiss watch manufactures, founded in 1865 by the 22-year-old Georges Favre-Jacot in Le Locle (canton of Neuchâtel). It was the first vertically integrated “manufacture” in Switzerland, bringing every craft under one roof, and its most famous product is the automatic high-frequency chronograph El Primero (calibre 3019 PHC, unveiled 10 January 1969, 36,000 vph, 5 Hz), saved by the master watchmaker Charles Vermot in a walled-off attic during the “quartz crisis.”
Besides watches and chronometers, during the stagnant 1910s Favre-Jacot diversified production into aneroid barometers and altimeters (“essentiellement destiné aux militaires”), which today are held in the collection of the Smithsonian National Air and Space Museum (e.g., the Simple Altimeter Type 05B and the British Mark V-A, ca. 1917); the key expert on them was Joël Duval (“ZEN”).
The company survived the collapse of the Russian market in 1917 (its most important pre-revolutionary market), the purchase by the American Zenith Radio Corporation (1972), the sale to Paul Castella’s Dixi group (1978), and, finally, its entry into LVMH in November 1999 for about USD 48.4 million; today Zenith is part of LVMH’s watch division alongside TAG Heuer and Hublot, and since 1 January 2024 it has been led by Benoit de Clerck.
Founding, Favre-Jacot, and the Birth of the Name
Georges-Émile Favre-Bulle was born in Le Locle on 12 December 1843. He left school at 9, became an apprentice to a watchmaker (by some accounts a “pivoteur”), and at 20 married Louise-Philippine Jacot-Descombes, a watchmaker’s daughter, after which he took the surname Favre-Jacot. Using his wife’s dowry, in 1865, at the age of 22, he founded his own workshop in the Les Billodes quarter.
Favre-Jacot’s key idea was to abandon the traditional fragmented “établissage” system, in which parts were made by numerous outworkers and small workshops, and to bring every craft under one roof. He drew inspiration from American industry (Waltham, Elgin), which the Swiss had seen at the 1876 World’s Fair in Philadelphia. The industrial complex of about 17,000 m² was connected to the Le Locle railway station for direct supply of raw materials. The factory was largely completed by 1881. In the early decades of the 20th century the manufacture employed up to 2,000 workers; by 1925 about 1,000, and Zenith was nicknamed “the manufacture with 2,000 golden and silver hands.”
Favre-Jacot was also a notable figure in architecture: he commissioned his villa (Villa Favre-Jacot) in Le Locle from the young Le Corbusier; he also worked closely with the architect Alphonse Laverrière.
Chronology of company names:
Besides “Zenith,” Favre-Jacot registered dozens of trademarks and logos: “Billodes,” “Diogenes” (1885), “Sentinelle,” “Marguerite,” and “Pilote” (1888) — a far-sighted registration thanks to which Zenith remains to this day the only brand entitled to write “Pilot” on a dial; also “Terminus” (1894), “Defi” (1902, later becoming “Defy”), the names of precious stones, as well as marks in Russian, Chinese, Arabic, and Finnish.
From Pocket Watches to Onboard Instruments
At first Favre-Jacot made precision pocket watches under his own name. Around 1900 the range expanded: on-board chronometers, table clocks, precision pendulum clocks, and later marine chronometers and Neuchâtel longcase clocks (neuchâteloises) with an 8-day carillon and, on request, a quarter repeater. The first pocket chronograph dates to 1899. After the First World War, Zenith began developing wristwatches, including alarm and chronograph functions, as well as trench watches; in 1915 the Land & Water model appeared, made exclusively for the London jeweller Birch & Gaydon.
The French aviator Louis Blériot was the first to fly across the English Channel on 25 July 1909 (Calais/Les Baraques — Dover, about 40 km); according to the Smithsonian NASM, the flight took 36 minutes 30 seconds. On his wrist Blériot wore a Zenith watch. In a letter of thanks dated 19 March 1912 (quoted by Monochrome Watches), Blériot recommended Zenith’s precision: “Je suis très satisfait de ma montre Zenith, je l’utilise régulièrement et je ne saurais trop la recommander aux personnes qui ont le souci de l’exactitude” (“I am very satisfied with my Zenith watch, I use it regularly and cannot recommend it too highly to anyone who cares about accuracy”).
Famous calibres:
Modern collections: Chronomaster (from 1994, the signature line with the tricolour El Primero counters), Defy (its origins lie in the sporty water-resistant model of 1969; the current line-up includes the Defy El Primero 21 with a 1/100th-of-a-second chronograph, Defy Skyline, Defy Extreme, Defy Revival), Pilot (Type 20 and others), Elite. The aviation flagship is the Pilot Montre d’Aéronef Type 20 (2012, 57.5 mm in diameter), based on onboard clocks of the 1930s.
From the earliest days of aviation, Zenith made not only wristwatches but also onboard instruments: altimeters and stopwatches.
Zenith Barometers and Altimeters
In the opening post of the thread “Le baromètre Zenith, une pièce de haute précision” on forumamontres.forumactif.com (13 August 2015), the forum administrator “ZEN,” Joël Duval (the key expert on Zenith barometers and altimeters, founder of forumamontres, creator of the ZenitHistoric and Hourconquest websites, and author of a monograph on Zenith), writes: “Dans le début des années 1910, l’horlogerie tend à stagner et les ventes sont difficiles. Georges Favre Jacot diversifie les activités et fabrique un Altimètre essentiellement destiné aux militaires. De l’altimètre au baromètre, il n’y a qu’un pas…” — that is, in the early 1910s the watch market was stagnating and sales were difficult, so Favre-Jacot diversified production, beginning to make an altimeter intended mainly for the military; from altimeter to barometer is but a single step.
We thus learn that the Swiss Zenith produced barometers and altimeters itself — a diversification of the core watch business, begun by Georges Favre-Jacot in the early 1910s to offset falling watch sales and preserve jobs; production is documented up to the 1930s, after which the instruments disappeared from the manufacture’s catalogue “despite their international success.”
The following instruments signed as Zenith are documented:
Despite the conventional design of their cases, Zenith instruments possess a distinctive charm thanks to their movements. The defining feature of the Zenith movement is its watchmaker-level construction and finish: a nickel-plated decorative plate with scalloped edges, a sculptural pointer-shaft bridge of characteristic asymmetrical, almost axe-shaped form, whose main body consists of a broad arched plate supported on several pillars above the baseplate, while motion is transmitted to the pointer shaft by a chaînette chain in the manner of a fusee mechanism. It is precisely this watch-like architecture, rather than the case itself, that makes a Zenith movement instantly recognizable.
The Russian Trail
The Russian market was one of the most important for the Favre-Jacot firm. From the 1870s the founder himself travelled to sell watches, including to Russia; from the turn of the century this was handled by Jämes Favre, who sold watches “to North and South America, Russia, India, China, and Japan.” A branch opened in Moscow in 1908, and the mark was officially registered in Russian; as early as 1902 Favre-Jacot registered the mark “Rainbow” in Russian. Tellingly, in 1909 a Russian subject, Ossip (“Osher”) Cheifetz from Warsaw, was appointed a director of Zenith SA.
Pre-revolutionary Zenith/Billodes/G.F.J. pocket watches made for the Russian market are a notable collecting category (documented, in particular, by WatchUSeek members). Among the documented examples:
The Russian Revolution of 1917 wrecked Zenith’s most important market. Combined with the post-war crisis, this forced the company to introduce shortened working hours and lay off part of its staff, which caused resentment among loyal workers. Annual revenue fell from 800,000 francs to just 37,000 francs in the period 1922–1924; the board accused Jämes Favre of mismanagement, and in 1925 he was ousted (per Grail Watch — gradually from 1923, definitively by 1925). Management passed to Ernst Strahm (from Vulcain) and technical director Fritz Cosandier.
Zenith had no direct links to Soviet industry, yet an “echo” of the brand exists: first, across the post-Soviet space there is a flow of “Zenith-style” fakes (including bogus “calibre 135s”); second, some collectors point to Soviet copying attempts (for example, references to Vostok watches supposedly using movements derived from Zenith cal. 135) — but these claims are unreliable and lack documentary confirmation. The coincidence with the Soviet “Zenit” camera is purely nominal.

Leadership (per Grail Watch and LVMH): Georges Favre-Jacot (1865–1911) → Jämes Favre (1911–1924/25) → Ernest Strahm (1924/25–1933) → Edgar Bichsel / Georges Perrenoud (Dixi, 1930s–1940s; during the Second World War Zenith and Dixi produced fuzes for munitions, which led to sanctions and inclusion on the Allied “blacklist”) → Jean-Pierre de Montmollin (1949–1972) → the Zenith Radio period (1972–1978) → Dixi/Paul Castella (1978–1999) → LVMH: Michel Manfredini (until 2001), Thierry Nataf (2001–2009), Jean-Frédéric Dufour (2009–2014, later CEO of Rolex), Aldo Magada (2014–2017), Julien Tornare (2017–2023, who “awakened the sleeping beauty”), and since 1 January 2024 — Benoit de Clerck (previously commercial director of Panerai and president of IWC in North America). LVMH’s watch division (TAG Heuer, Hublot, Zenith) has been led since 2024 by Frédéric Arnault.
Current Status
Officially, Zenith today operates as ZENITH, a branch of LVMH Swiss Manufactures S.A., at 34 rue des Billodes, Le Locle. Through LVMH’s official profile and its official announcement of appointments, it is confirmed that the brand belongs to LVMH’s Watches & Jewelry division and that the acting CEO is Benoit de Clerck, who succeeded Julien Tornare.
Operationally, Zenith remains a full-fledged manufacture. The brand’s official pages emphasise that all its modern watches are fitted with mechanical movements developed and produced in-house at Zenith, and that the company is active in more than 50 countries and works with around 600 movement variations. In practice this confirms that Zenith today is not merely a heritage brand in the LVMH portfolio, but an operating production platform in the high-end watch segment.
