Spot quartz battery leak and corrosion early, then act before it damages the movement.
If you see crusty residue or green/white corrosion near the battery area on a stopped quartz watch, treat it as a high-urgency leak risk. Stop using it and seek professional cleaning before corrosion spreads.
1. Stop casual wear if leak signs are visible.
2. Do not scrape residue into the movement.
3. Keep the watch dry.
4. Book battery replacement and professional cleaning quickly.
5. Ask the shop to inspect for corrosion on contacts and nearby parts.
Only a technician who opens the case can confirm leakage and clean it safely. Visible clues raise urgency; absence of clues does not guarantee a healthy cell forever.
