Le Locle Sport at Its Most Defiant
What Zenith sport series from the 1970s captured the manufacture's engineering spirit in its most angular form?
The Zenith Defy was built at the same time the brand’s engineers were developing the El Primero — one of the greatest movement achievements in Swiss horology. That technical culture permeates every Defy: robust, purposeful and made without compromise in Le Locle. A 1972 Defy is a genuine piece of Zenith heritage at a fraction of the El Primero’s price.
Defiance, built in Le Locle since 1865.
The 1972 Zenith Defy is the kind of vintage Swiss sport watch that rewards collectors willing to look beyond the obvious. Its angular character, Le Locle manufacture credentials and era-defining design make it an honest and deeply appealing piece of watchmaking history.
