The legendary El Primero Calibre
A Revolution in the world of watches
The Swiss watch manufacturer Zenith is based in Le Locle and has produced quality timepiece for over 150 years. Zenith watches are renowned for their excellent and innovative mechanics. The factory from Switzerland continues to prove time and again that a passion and a pioneering spirit for watchmaking are the leading philosophies of the distinguished Zenith brand.
In 1969, Zenith released the world’s first automatic chronograph movement with an integrated movement construction. Suitably, Zenith named the innovative movement with the name El Primero – meaning ‘the first’ in Esperanto. The pioneering features of the El Primero took seven years to develop. The overall structure of the movement is comprised of a column wheel and a central rotor mounted on ball bearings.
The original ambition behind the El Primero was to create an iconic timepiece that could be presented to watch lovers worldwide on the 100th anniversary of Zenith, which became a Manufactory in 1965. A revolution in the watch industry, the El Primero impresses with a tempo of 36,000 vibrations per hour and is therefore distinguished as the most precise timepiece available to the watch loving market. The movement of the El Primero testifies to the craftsmanship and longevity of Zenith timepieces, which have been continually developed and improved over the years. The name Zenith is now recognised worldwide, due in part to the impressive development of the El Primero movement. The El Primero watch line is now one of the most important collections from the watch brand and stands for the unyielding development and advancement of the company.
