From the court to the wrist

The partially open dial with closed chronograph counters as well as the Cordura-effect rubber strap are treated in a blue tone, matching the tennis courts of the Ultimate Tennis Showdown tournament. Touches of yellow are applied in the same tone as the ubiquitous tennis ball. For some words of wisdom from the coach himself, the rim of the carbon bezel is engraved and filled in luminescent pigments with a motto Patrick Mouratoglou lives by: “Little details make big differences”.



A high-frequency revolution. The El Primero 21 is the culmination of over 50 years of perfecting the automatic chronograph at the Zenith manufacture. Equipped with two regulating organs and escapements, one beating at 5Hz for timekeeping, and the other at an incredible 50Hz to offer a true 1/100th of a second chronograph display, the El Primero 21 is the chronograph calibre of the 21st century.
