Zenith was founded in Le Locle in 1865 and remains one of the few Swiss manufacturers to develop, produce and assemble its movements entirely in-house. The brand's defining achievement is the El Primero calibre, introduced in 1969 as one of the first automatic chronograph movements ever produced, beating at 36,000 vibrations per hour for greater precision in elapsed time measurement. That calibre, in various iterations, remains the technical backbone of the Chronomaster collection to this day and is widely regarded as one of the most important movements in the history of Swiss watchmaking.
