Citizen watch batteries
Citizen quartz answers live on the movement / calibre stamped on the caseback — not the marketing model alone. Match Cal. 0510 / 6329 / G112 (and siblings) below. Eco-Drive rechargeable cells are not CR/SR swaps.

Still not working?
Only after the correct calibre and cell: confirm the caseback movement number (left of the case number). Prefer a dealer for water-resistant reseal. If the watch is Eco-Drive, stop — this resolver is for disposable quartz only.
