Brand History
Citizen
Founded in 1918, Citizen is one of the largest manufacturers of watches in the world and also one of few brands with a vertically-integrated production model, designing and manufacturing every component of all of the watches in Citizen’s vast offering. While perhaps best known for inexpensive, solar-powered watches from the Eco-Drive collection, Citizen also has a powerful enthusiast following largely associated with the Promaster collection of divers and tool watches best exemplified by the Aqualand diver’s watch.
