Zenith EL PRIMERO series, Руководство по эксплуатации

Страница: 11 / 89

You are looking at the most famous movement
in watchmaking history, a movement familiar to
every aficionado and currently the most accurate
mass-produced movement in the world. Its secret
lies in the frequency of its balance. While most
oscillate at a rhythm of 8 vibrations per second,
the El Primero calibre performs 10 vibrations in the
same time. Its development gave rise to numerous
major inventions, and its power reserve had to be
optimised to compensate for the increased energy
consumption caused by this higher oscillating
rate. All Zenith watches are equipped with a Zenith
Manufacture movement. There are few brands
in the world that can pride themselves on having
an approach as rigorous as ours. From the very
moment you invest in a Zenith watch, you can be
absolutely certain that you are in possession of a
watch that has been produced from start to finish
at the Le Locle Manufacture. This fundamental
requirement imposed a need for calibres that led to
the creation of more than 600 different movements.
