Chronomaster Sport

ZENITH EXPANDS THE CHRONOMASTER SPORT WITH A TWO-TONE STATEMENT

The CHRONOMASTER Sport stands at the intersection of legacy and forward momentum. Born from the El Primero, the world’s first automatic, integrated high-frequency chronograph calibre, it carries more than five decades of precision within its architecture. This new steel and rose gold edition introduces a different expression of that same intensity. Not a departure from its sporting roots, but a shift in tone where performance is conveyed with restraint rather than force. It is a chronograph designed to move seamlessly across contexts, retaining its mechanical authority while adapting effortlessly to its surroundings.

This evolution takes shape first through its construction. The 41mm case preserves the sharp architecture and balanced proportions that define the CHRONOMASTER Sport, now executed in a two-tone construction that plays with contrast. The stainless steel build anchors the watch in technical robustness, while the rose gold bezel, crown and pushers introduce warmth and depth. The result is neither purely sporty nor overtly formal, but deliberately versatile, a watch equally at ease in motion as it is in more composed settings.

Beneath the sapphire crystal, the mother-of-pearl dial reveals a controlled luminosity, never ornamental, always deliberate. Light moves across its surface, subtly transforming the watch throughout the day. The signature 3-6-9 overlapping counters remain intact, a direct lineage to the original El Primero, while faceted hands and applied indexes ensure clarity and precision in all conditions.

At its core beats the El Primero 3600, operating at 5 Hz — 36,000 vibrations per hour. Its central chronograph hand completes one full rotation in 10 seconds, translating mechanical frequency into visible motion. The measurement of 1/10th of a second is not an added complication, but the natural consequence of its architecture.

Visible through the sapphire case back, the movement reveals its column wheel and horizontal clutch construction, alongside an openworked rotor engraved with the ZENITH star. Bi-directional winding delivers 60 hours of autonomy, sustaining the rhythm that defines the watch.

The integrated steel and rose gold bracelet extends this dialogue of contrast. Alternating brushed and polished surfaces emphasize its structure, while the rose gold center link echoes the bezel’s presence. Secured by a safety double folding clasp, it reinforces the watch’s adaptability and daily practicality.

Released in a limited edition of 50 pieces, this CHRONOMASTER Sport offers a refined perspective on high-frequency chronograph performance: Precise, composed and inherently versatile.

ZENITH: THE HEART OF WATCHMAKING

Founded in 1865 in Le Locle, Switzerland, ZENITH has been at the forefront of Swiss watchmaking for over 160 years, driven by a pioneering spirit and a relentless pursuit of precision. As the first vertically integrated Swiss watch manufacture, ZENITH has continuously revolutionized horology by developing and manufacturing in-house movements, most notably the El Primero, the world’s first automatic, integrated high-frequency chronograph calibre launched in 1969, renowned for its unparalleled precision and high-frequency performance.

ZENITH’s timepieces celebrate its dedication to innovation and exceptional craftsmanship. The CHRONOMASTER collection embodies the expression of mechanical excellence and watchmaking versatility, the DEFY showcases technical innovation and bold design, while the PILOT collection celebrates ZENITH’s storied aviation legacy with distinctive, adventure-ready timepieces. This unwavering commitment to precision has been recognized with an unparalleled 2,333 chronometry prizes, underscoring ZENITH’s enduring legacy of excellence. The Calibre 135, having won most of those prizes, went through a modern re-engineering integrating up-to-date technical solutions and materials. ZENITH decided to give it a new home in its newly introduced G.F.J collection.

Throughout its history, ZENITH timepieces have accompanied pioneers who dared to dream big and achieve the extraordinary: from Louis Blériot’s historic flight across the English Channel to Felix Baumgartner’s record-breaking stratospheric free-fall jump. This daring spirit continues to drive the Maison as it redefines the future of Swiss watchmaking. Celebrating over a century and a half of excellence, innovation, and purpose, ZENITH remains at the forefront of Swiss horology, empowering those who challenge conventions and strive for greatness.

From Le Locle to the world, from 1865 to now, ZENITH is the heart of watchmaking.
