Makers of the El Primero chronograph, one of the most legendary luxury watches in history, and the world's most accurate series-produced timepiece, Zenith watches is proud to declare that all of its timepieces include its own proprietary movements, and rightly so. Founded in 1865 by Georges Favre-Jacot, Zenith is proud of its precision and in-house work, and has received more than 2,000 awards for its luxury watches - quite literally a world record. Retaining an air of sophistication on the outside and intricate movements within, it's not hard to see why patrons as diverse as Mahatma Gandhi and Roald Amundsen have chosen this renowned brand.
