Zenith Watches: Horological Excellence & Market Value

A Swiss Manufacture at the Forefront Since 1865

Founded in 1865 in Le Locle, Switzerland, by Georges Favre-Jacot, Zenith is one of the oldest watch manufactures still in operation today.
From its very beginnings, the house stood out for its visionary philosophy: bringing together all the watchmaking crafts under one roof a revolutionary concept at the time.

This integrated approach allowed Zenith to control the entire process of design, production, and assembly.
Synonymous with chronometric precision, the brand quickly gained international recognition its calibers have won over 2,300 observatory prizes from the late 19th to the 20th century.

The Genius of the El Primero Caliber

The year 1969 marked a decisive milestone in Zenith’s history with the creation of the El Primero caliber — the first high-frequency automatic chronograph (36,000 vibrations per hour).
This revolutionary movement offered unmatched precision and the ability to measure one-tenth of a second, a unique technical feat at the time.

The El Primero quickly became an industry benchmark, used not only in Zenith watches but also by other prestigious brands including Rolex, which equipped its Daytona models with it between 1988 and 2000.

Even today, the El Primero remains the beating heart of many Zenith collections, appearing in modern versions such as the Chronomaster, Defy El Primero 21, and Chronomaster Sport.

Design and Identity: Between Tradition and Innovation

Zenith’s identity lies in the balance between authentic Swiss craftsmanship and technical innovation.

Its flagship collections embody this duality:

• El Primero Chronomaster — iconic chronographs, often with a tri-color dial and a transparent caseback showcasing the movement.

• Defy — a more avant-garde line, emphasizing open-worked designs, modern materials (titanium, carbon, ceramic), and spectacular complications.

• Pilot — aviation-inspired watches with large Arabic numerals and vintage styling.

• Elite — classic dress watches combining slimness and urban elegance.

Zenith continues to produce all its movements in-house, a guarantee of quality and exclusivity, true to its founder’s motto:

“Always follow the star to reach perfection.”
