Zenith, the Le Locle-based watchmaker striving for the highest level of precision

In 1865, Georges Favre-Jacot founded the Fabrique des Billodes in Le Locle

In 1865, at the age of just twenty-two, Georges Favre-Jacot founded the Fabrique des Billodes in Le Locle, in the Swiss canton of Neuchâtel.

This young, visionary entrepreneur brought together under one roof all the trades necessary for watchmaking—a revolutionary industrial model at the time that foreshadowed the modern integrated watch manufacture.

All watchmaking trades under one roof: a visionary factory

The industrial model developed by Georges Favre-Jacot, inspired by the large American factories of his time, broke with the traditional “établissage” system, in which each component was subcontracted to scattered artisans.

This centralized organization under one roof improved quality control and accelerated production cycles—crucial competitive advantages for conquering international markets.

1911: The Manufacture Officially Adopts the Name Zenith

In 1911, the watchmaking company officially adopted the name Zenith, a term chosen for its connotations of excellence and ambition; in astronomy, the zenith refers to the highest point of the celestial sphere. This name, which is short and pronounced the same way in all languages, is a valuable commercial asset for an ambitious watchmaker whose timepieces are exported worldwide.

Georges Favre-Jacot, a pioneer of integrated watchmaking

An industrial workshop inspired by large American factories

Georges Favre-Jacot’s study trip to the United States, where Taylorism was beginning to transform the manufacturing industry, directly inspired the organizational model he implemented in Le Locle.

This American inspiration, applied to Swiss watchmaking, represented a managerial innovation as much as a technical one, and would prove decisive for the manufacture’s competitiveness in international markets.

The Quest for Records at Chronometric Observatories

From its very earliest years, the Zenith manufacture engaged in technical competition with other major Swiss manufacturers by participating in chronometry competitions organized by astronomical observatories. These competitions, which recognized the accuracy of the movements under examination, enabled Zenith to accumulate a record number of awards, directly contributing to its reputation for technical excellence.

A Star and a Name Chosen to Aim for the Zenith of Watchmaking

The five-pointed star logo, associated with the name Zenith since the brand’s inception, visually embodies the Manufacture’s enduring ambition to aim for the highest standards in watchmaking precision. This instantly recognizable symbol is one of the identifying features of a Zenith watch when examined by an expert.

El Primero, the first automatic chronograph in history

January 10, 1969: Zenith unveils a self-winding chronograph

On January 10, 1969, at a press conference in Le Locle, Zenith unveiled the El Primero, the first self-winding chronograph movement in the history of watchmaking. This unveiling, which took place a few weeks before that of its direct competitors, earned the manufacture official recognition as the creator of this invention, which would revolutionize the luxury sports watch market.

36,000 vibrations per hour: high frequency at 1/10th of a second

The El Primero’s defining feature lies in its high oscillation frequency—36,000 vibrations per hour, compared to 18,000 for traditional chronograph movements—enabling time measurement to the nearest tenth of a second rather than the nearest fifth of a second. This technical superiority, still relevant today, is the main selling point of Zenith watches equipped with this caliber.

“El Primero,” the first—a name that has become a legend in watchmaking

The name “El Primero,” which means “the first” in Spanish, was chosen to highlight Zenith’s chronological primacy in the invention of the automatic chronograph. This name has since become synonymous with excellence in the world of chronography, recognized as a technical benchmark by all professionals and enthusiasts of mechanical watchmaking.

Charles Vermot, the watchmaker who saved El Primero from the quartz crisis

1975: The Order to Destroy the Machinery for Mechanical Movements

In 1975, at the height of the quartz crisis that threatened the very existence of mechanical watches, Zenith’s management ordered the destruction of all the manufacturing tools for mechanical movements—including those for the El Primero—in order to focus exclusively on quartz production.

The presses and blueprints hidden behind a partition in the factory

Charles Vermot, a watchmaker at the manufactory, refused to obey this order. He discreetly hid the blueprints and some of the El Primero tooling behind a false partition in the factory’s attic, thereby preserving what would prove to be the company’s most precious technical heritage.

1984: The Rebirth of the El Primero and the Zenith-Powered Daytona

In 1984, when Rolex was seeking a chronograph movement to power its Daytona, Zenith was able to retrieve the El Primero’s plans and tooling thanks to Charles Vermot’s efforts. This providential order revived production of the legendary caliber, whose value has continued to rise ever since.

Zenith’s manufacturing expertise, from the movement to the dial

A watch movement designed, developed, and assembled in-house

Zenith is one of the few watch manufacturers to design, develop, and assemble all of its movements in-house, without relying on external components or off-the-shelf calibers.

It is this complete vertical integration that guarantees total technical and aesthetic harmony between the movement and the case—a quality appreciated by the most discerning collectors.

Automatic watches, chronographs, and in-house complications

The manufacture masters the entire spectrum of watchmaking complications, from the simplest automatic watches to the most sophisticated chronographs, including tourbillons and skeleton watches. This technical versatility is a major commercial asset and contributes to the diversity of prices on the secondary market.

Skeleton Watch: The Heart of the Movement Revealed on the Dial

Skeleton watches, which expose the movement so it is directly visible through the dial, represent one of the most spectacular and sought-after segments of Zenith’s production. These timepieces, which require an exceptional level of finishing to be visually appealing, generally command a higher value than models with traditional dials featuring the same caliber.

The Iconic Collections That Make Zenith So Popular

Chronomaster, the direct successor to the 1969 El Primero

The Chronomaster collection is the most direct contemporary interpretation of the historic El Primero, offering a modern take on the three-color dial aesthetic characteristic of the original caliber. This collection enjoys strong demand on the pre-owned market, driven by the aura of the legendary caliber it houses.

Defy, high frequency pushed to 1/100th of a second

The Defy collection, in its most recent versions, pushes the limits of high frequency to 1/100th of a second, surpassing even the already remarkable precision of the El Primero. These technically cutting-edge creations enjoy a reputation for modernity in the luxury sports watch market.

Pilot and Elite: From Pioneering Aviation to Ultra-Thin Watches

The Pilot collection, whose historical roots are tied to the early days of aviation, and the Elite collection, the embodiment of ultra-thin elegance, round out Zenith’s product lineup, offering collectors stylistic alternatives to the predominantly sporty Chronomaster models.

How to Identify and Authenticate a Zenith Watch

Serial Number, Model Number, and El Primero Caliber Signature

Every Zenith watch bears a unique serial number and a model reference number, allowing an expert to identify it precisely in the manufacturer’s catalog. The presence of the El Primero caliber—identifiable by its frequency of 36,000 A/h—is a key technical criterion for authentication.

Original Case, Dial, and Movement: Hallmarks of Value

The consistency between the case, dial, and movement of a Zenith watch is a key point of scrutiny for the expert, as certain parts may have been replaced over the course of the watch’s history.

Certificate, case, and purchase documents should be carefully preserved

Preserving the certificate of origin, the presentation box, and the purchase documents significantly enhances the estimated value of a Zenith watch.

What Determines the Value of a Zenith Watch

Model, caliber, and rarity: a vintage El Primero does not command the same value as a standard model

The model and caliber are the primary factors determining value; a vintage El Primero from the early generations commands a much higher price than standard models, due to its historical significance and rarity.

Case material, complications, and condition

The case material, the nature of the watch complications, and the overall condition of the movement and dial are additional factors considered by the expert.

Provenance, original documentation, and market demand

Documented provenance and current market demand for the model in question are the final factors in determining the final valuation.

Vintage watches, limited editions, and recent models: What’s their value?

Vintage Zenith: The El Primero A386 and Vintage Dials Are Highly Sought After

The El Primero A386 models, the first versions of the legendary caliber produced starting in 1969, are the most sought-after pieces on the vintage Zenith market, particularly due to their distinctive tricolor dials and their historical significance in mechanical watchmaking.

Limited Editions and Discontinued Models, Highly Sought-After at Auctions

Limited editions and discontinued models command a significant premium for their rarity on the secondary market, with their value generally rising as the number of available pieces decreases.

Recent Models and the Chronomaster: An Active Pre-Owned Market

Recent models and the Chronomaster fuel an active pre-owned market, offering collectors a more accessible entry point into the world of Zenith.
