CITIZEN. BN4021-02E Promaster Altichron Citizen Watch.
CITIZEN WATCH is a true manufacture d'horlogerie with a comprehensive manufacturing process that extends from creating a watch’ s individual components to its final assembly. The company operates in more than 100 countries around the world. Since its founding in 1918, CITIZEN have held the belief of “Better Starts Now” - that is, no matter who you are and what you do, it is always possible to make something better, and now is the time to start doing it. Sharing this belief, we have made watches, invented and improved technologies and explored the future of watches such as our proprietary light-powered Eco-Drive technology, and satellite-synchronised timekeeping system Satellite Wave .

ECO - DRIVE
The clock that never stops, wherever you are.
One of Citizen's challenges: to develop a technology that guarantees the continuity of the clock's operation, anywhere in the world. In 1976, we invented the first light-fed analog quartz watch that works exclusively using light as a source of energy. This technology, now known as Eco-Drive, can generate energy from any light source (artificial light, natural light and even in dim light) to continue the operation of the clocks without replacing the battery.
Beyond the limits of matter.
This is the decisive step that Citizen has taken to improve the extraordinary characteristics of a mineral such as titanium. The Super Titanium of Citizen maintains the great lightness typical in titanium but, thanks to an exclusive process its resistance is five times higher.
