Answer a few questions and get the most likely cause band plus what to do next. Educational triage only — not a workshop diagnosis.
1. Confirm crown is fully in / screwed down.
2. For manual/auto: wind gently 20–30 turns if safe for the watch.
3. For automatic: wear or use a winder after winding.
4. For quartz: consider battery replacement first.
5. If it was dropped, avoid forcing the crown or pushers.
This tool gives likely cause bands only. Broken staffs, magnetism, dried oil and keyless faults can look similar from the outside.
Why did my automatic watch stop?Often low power after insufficient wear or storage. Shock, service needs or crown position can also cause stops.
My watch stopped after winding. Why?Could be crown not fully engaged, over-stress after shock, or an internal fault needing inspection.
Can magnetism stop a watch?Magnetism more often makes it run fast. Full stop is less typical as the first clue, but still get it checked if behaviour is abnormal.
When should I service it?If safe power/crown checks fail, if it was dropped, or if running becomes unreliable.
