Redaktioneller Text auf Englisch.

LVMH-owned manufacture in Le Locle, founded by Georges Favre-Jacot in 1865. Best known for the El Primero, a 36,000 vph automatic chronograph calibre unveiled in 1969 and used today in the Chronomaster and Defy lines, alongside Pilot and Elite models. Core prices sit around EUR 8,000–16,000.

Geschichte

Georges Favre-Jacot was 22 when he set up a watchmaking workshop in Le Locle in 1865. Instead of relying on scattered home workers, he brought the trades together in one manufacture at Les Billodes, and after visiting the 1876 Centennial Exhibition in Philadelphia he adopted American factory methods. A calibre named Zenith won a Grand Prix at the 1900 Paris World's Fair, and in 1911 the company definitively adopted Zenith as its name, with a star as emblem.

Precision became the firm's calling card. The Calibre 135 of 1948 collected 235 chronometry prizes, and its competition version, the 135-O, won five Neuchâtel Observatory prizes between 1950 and 1954. Zenith bought the movement maker Martel in 1959. In the United States its sales were held back by the name clash with Zenith Radio, and in 1968 it merged with Movado, later adding Mondia, to sell there under the established Movado name.

Work on an automatic chronograph began in 1962 with the company's centenary in view. The El Primero was unveiled on 10 January 1969: an integrated automatic chronograph beating at 36,000 vibrations per hour, fast enough to time tenths of a second. In 1972 Zenith Radio took over the Swiss company and pushed it towards quartz. In 1975 watchmaker Charles Vermot hid the El Primero tools and plans in the attic of the Ponts-de-Martel site instead of scrapping them, which allowed production to restart in 1984.

Dixi bought the group from Zenith Radio in 1978, and the revived El Primero found outside customers: Rolex used a modified version in the Cosmograph Daytona from 1988 to 2000. The slim Elite calibre followed in 1994, and LVMH bought Zenith in November 1999. The Defy El Primero 21 of 2017 added a second escapement for hundredths of a second, and the Chronomaster Sport of 2021 brought a tenth-of-a-second chronograph into the core range. Zenith counts more than 2,300 chronometry prizes.

Drei Dinge, die Sammler wissen

Rolex's chronograph supplier

From 1988 to 2000 Rolex used a modified El Primero in the Cosmograph Daytona. Rolex replaced it with its own Calibre 4130 in 2000.

Why 36,000 vph matters

At 36,000 vibrations per hour the El Primero's balance beats ten times a second, so the chronograph can show tenths of a second rather than the eighths of a 28,800 vph movement.

The radio maker that bought it

Zenith struggled to sell under its own name in the US because of Zenith Radio. The radio company then bought the Swiss firm in 1972 and moved it towards quartz.
