Package Contents

1 × MT621 rechargeable battery with dedicated connection tab.

Citizen movements use different rechargeable cells, contact plates, terminal tabs, and part numbers. Please confirm the movement calibre, original battery code, Citizen part number, terminal orientation, and connector shape before ordering. A bare MT621 cell may not directly replace an assembly fitted with model-specific connector plates.

Do not substitute a disposable alkaline or silver-oxide battery. The movement’s charging circuit is designed for a compatible rechargeable cell and may damage an unsuitable battery or the watch.

Professional installation, system resetting, and sufficient initial light charging may be required after replacement.
