ZENITH the EL Primero Lightweight Limited Edition

An avant-garde sports model

Zenith focuses firmly on lightness, daring and innovation in an exclusive version of its El PRimero Striking 10^th chronograph featuring high-tech materials. Issued in a 100-piece limited edition, the El Primero Lightweight model teams a titanium and silicon movement with an ultra-sporty carbon case. It signals the dawn of a new era in the fabulous history of the legendary El Primero calibre.

At the time of its launch in 1969, the El Primero calibre overturned existing conventions by asserting itself as the first-ever automatic chronograph to boast an integrated construction. Also impressing observers by beating at the exceptional frequency of 10 vibrations per hour (36,000 vibrations per hour), it is still the world’s most precise series-made chronograph calibre. Over the years, Zenith has steadily fine-tuned its legendary movement in order to optimise its precision, its reliability and its performance. The brand with the guiding star has also taken up the challenge of associating its high-frequency chronograph with other complications such as the tourbillon, the perpetual calendar and the split-second function. In 2010, Zenith reinvented the “jumping seconds” in presenting the El Primero Striking 10^th. Equipped with a sweep seconds hand making ten jumps per second and a complete turn of the dial every ten seconds, this chronograph not only measures but also displays tenths of a second with extreme precision. To enhance the performance of this mechanism requiring a considerable amount of energy, the Manufacture from Le Locle notably fitted it with a double chronograph wheel in silicon, a material three and a half times lighter than classic alloys.
