Eco-Drive is not ordinary battery quartz
Light energy is stored in a rechargeable power system, so diagnosis should begin with charging history and movement behavior rather than treating the watch as if it simply needs a disposable cell.
Citizen quartz can still need movement work
Conventional Citizen quartz watches can have the same battery, movement, hand and corrosion issues found in other quartz brands.
Case parts are model-specific
Crystals, crowns, pushers and bracelets depend heavily on the model. A clear caseback and dial photo help.
Older Citizen watches are welcome
Mechanical and vintage Citizen models are reviewed based on caliber, parts availability and condition.
