<p>The Zenith Chronomaster Sport was introduced in 2021 as an updated take on the brand's iconic El Primero chronograph. The Chronomaster Sport blends hints of important chronograph watches of days gone by with clear-cut lines and up-to-date materials, resulting in a watch that feels timeless yet entirely modern. Power comes from the self-winding caliber El Primero 3600. One of the unique features of this movement, is a central seconds hand for the chronograph which rotates once every 10 seconds.</p> <p>The Zenith Chronomaster Sport reference 18.3101.3600/69.M3100 is a new 2022 addition. Arguably the King of the Chronomaster Sport line-up, this watch has a full rose gold case and matching bracelet.</p>
