Chronomaster Original

The result of 50 years of gradual improvement and a true mastery of the automatic high-frequency chronograph movement, the Chronomaster Original is equipped with the latest version of the El Primero calibre, dubbed the El Primero 3600. With its high frequency of 5 Hz (36’000 VpH), the movement is able to precisely offer a true 1/10th of second indication. Its autonomy has also been rendered more efficient, with an extended power reserve of 60 hours. Visible through the sapphire display back, the new architecture features a sleeker and more open design, revealing a blue column wheel and open rotor marked with the five-pointed star Zenith.
