It’s more than a timepiece, it’s a technology...Eco-Drive Technology!  

This stainless steel, water resistant watch is specially powered by Citizen’s proprietary ECO-DRIVE TECHNOLOGY, which converts any source of light (natural and artificial) into usable energy.  This harnessed energy is then stored in a special power reserve to keep the watch charged and running properly.  When fully charged, the Citizen Eco-Drive will continue running- even in total darkness- for at least six (6) months.  Properly maintained, it will never need another battery!
