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 295-series 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.
