This Zenith Class Sport Chronograph perfectly blends refined Swiss craftsmanship with bold sport-watch styling. Featuring a robust 44mm stainless steel case with a polished bezel, this timepiece houses the legendary El Primero Caliber 400 — a high-frequency automatic chronograph movement beating at 36,000 vph for 1/10th second precision. The exhibition caseback reveals the beautifully finished movement with Geneva stripes, gold rotor engraving, and the unmistakable engineering Zenith is known for.

The black dial offers exceptional legibility with large applied Arabic numerals, luminous hands, and a balanced tri-compax subdial layout. A tachymeter scale runs along the outer chapter ring, and a discreet date window sits between 4 and 5 o’clock. The chronograph pushers operate with crisp precision, a hallmark of the column-wheel El Primero movement.

Completing the look is a black alligator leather strap with contrasting white stitching, secured by a Zenith-signed stainless steel deployant clasp for comfort and security. With 50m water resistance and versatile styling, it’s equally at home under a cuff or on a casual weekend.
