Key Features

• Automatic Chronograph Movement: At the heart of this watch lies the iconic El Primero caliber, a high-frequency automatic movement developed entirely in-house by Zenith. Known for its exceptional accuracy and smooth sweep of the seconds hand, this movement operates at 36,000 vibrations per hour—one of the highest frequencies in mechanical watchmaking. This results in precise 1/10th-of-a-second timing capability, a feature highly valued in professional and recreational timing applications.
• Distinctive Dial Design: The dial presents a classic tri-compax layout with three sub-dials: a 30-minute counter at 3 o’clock, a 12-hour counter at 6 o’clock, and a continuous seconds display at 9 o’clock. A date window at 6 o’clock adds everyday practicality, while luminous hour markers and hands ensure clear legibility in dim lighting. The balanced arrangement and refined typography reflect both functionality and visual harmony.
• Swiss-Made Craftsmanship: Manufactured and assembled in Switzerland, this watch adheres to the strictest standards of Swiss watchmaking. Each movement undergoes meticulous hand-finishing, and every component is inspected for quality and precision. The result is a timepiece that embodies the tradition, expertise, and attention to detail for which Swiss horology is renowned.
• Sporty yet Refined Aesthetic: With its clean lines, balanced proportions, and versatile color palette, this watch transitions effortlessly between formal and casual settings. Whether paired with a business suit or worn during weekend activities, it maintains a presence that is both understated and commanding. The design honors its racing heritage while remaining relevant in contemporary fashion.
• Durable Construction: The case and crystal are engineered to endure the rigors of daily wear. While specific material details are not provided, the overall build reflects Zenith’s commitment to longevity and resilience. The watch is designed to maintain its appearance and performance over years of regular use, making it a reliable companion for active lifestyles.
