About Zenith

Time To Reach Your Star

With roots as far back as 1865, Zenith was one of the first Swiss brands to integrate all aspects of the watchmaking process under one roof, from case manufacture to movement production to final casing and assembly. With a rich history of watchmaking in the purest sense, Zenith is responsible for the world’s first automatic chronograph caliber. Today, Zenith is known for its technically avant-garde approach to watchmaking, incorporating age-old knowhow with modern materials and manufacturing processes to produce innovative, beautiful timepieces.
