• Eco-Drive    A watch that never needs a battery. Citizen Eco-Drive technology harnesses the power of light - from any natural or artificial light source - and converts it into energy which is stored in a permanently rechargeable lithium-ion battery. It recharges continuously in any kind of light to run forever. The power reserve stated for each watch is once fully charged.  • Perpetual Calendar    Automatically adjusts for odd and even months and leap years through to 2100  • Perpetual Calendar Eco-Drive    Automatically adjusts for odd and even months and leap years through to 2100, 300-day power reserve (Ladies models - 2 year power reserve).  • Promaster    Promaster watches undergo rigorous safety tests and fulfil the stringent quality standards on water and shock resistance, visibility and strap strength, as determined by the International Organisation for Standardisation (ISO 6425).  • Stiletto    Ultra thin 4.3mm, the thinnest light powered watches in the world.  • 5 Year UK Guarantee    Citizen watches are guaranteed against defects in material and workmanship for five years (UK only).

On DIVERS wathes, the word "Divers" is marked on the dial and/or caesback.  • Radio Controlled    Radio controlled watches recieve a time signal from a radio transmitter tuned to a caesium or 'Atomic Clock'. The atomic clock is the standard measure of time: the electron resonance frequency of the Caesium 133 atom is 9,192,631,770 cycles per second which is measured to give a time accurate to greater than +/- 1 second per million years. The transmitter signal is picked up by the watch and sets the time and date automatically  • Please call 0121 233 1801 if you have any further questions or to order any watch in the current Citizen range
