Futuristic precision without compromise
Zenith Defy
The Zenith Defy collection represents the pinnacle of technical innovation and avant-garde design in the brand's portfolio. It builds on the historic roots of the original range from the 1960s, but its current form is thoroughly modern - combining bold aesthetics, breakthrough technologies and cutting-edge precision.
The Defy collection is characterised by angular cases, often in titanium, carbon or ceramic, and skeletonised dials that reveal high-frequency El Primero movements or the revolutionary Defy Inventor calibre. Some models reach frequencies of up to 360,000 vibrations/hour (50 Hz), ensuring exceptionally accurate timekeeping.
The collection includes classic sports models as well as ultra-modern skeletons, chronographs with precision to the tenth of a second, and complicated pieces with tourbillon. The Defy Skyline, Defy Extreme or Defy Zero G push the boundaries of watchmaking in both technical and design terms.
The Zenith Defy is for those looking for distinctive and innovative watches that transcend convention and show the future of haute horlogerie - with an unwavering focus on performance, materials and movement architecture.
Traditional innovations of Swiss haute horlogerie
Zenith
Zenith is a prestigious Swiss watch brand, founded in 1865 by Georges Favre-Jacot in Le Locle. It was one of the first manufactures ever to bring all phases of watchmaking under one roof, laying the foundations for an integrated and innovative watchmaking industry. Today, the brand is best known for its legendary El Primero movement - the first automatic chronograph with a high frequency (36,000 A/h), introduced in 1969.
Zenith specialises in technical excellence, chronometric precision and pioneering spirit, which is reflected in iconic collections such as the Chronomaster, Defy, Pilot and Elite. Models often combine retro inspiration with modern engineering, using skeleton dials, avant-garde materials and featuring custom calibres.
The Zenith brand is for those looking for mechanical watches with soul, combining artisanal tradition with technological advancement. Each piece reflects the brand's philosophy: 'Time to reach your star'.
