Originally established in 1865 by watchmaker Georges Favre-Jacot, Zenith has been crafting fine timepieces of all kinds in the small Swiss city of Neuchâtel for over 150 years. Since their inception, Zenith produces its works entirely in-house, from design and creation to finalized and tested products. In more recent years, Zenith become known for its incredibly precise in-house movement, the El Primero. This caliber is widely recognized as one of the most sophisticated and accurate mechanical chronograph movements in the industry and is seen in many different models of Zenith chronographs. It was the El Primero caliber that helped Zenith come out of the quartz movement crisis at full speed, ready once again to produce fine mechanical watches. Today, Zenith watches are appreciated both for their functionality as well as their fine craftsmanship and elegant designs.
