An automatic watch relies on movement to wind its mainspring, so it may stop after sitting unworn. That does not always mean something is broken. Start with a few gentle checks: make sure the crown is in its normal position, wind the watch as its manual recommends, and wear it consistently for a while. Avoid forcing any part. If the watch remains still, loses time badly, or feels unusual, a professional diagnosis can help prevent further damage.
Check the Crown and Winding
Look at the crown, the small knob on the side of the case. If it is pulled out, the watch may be in a time-setting position rather than running. Push it in gently until it sits in its normal position. If the crown screws down, follow the watch’s instructions to unscrew and secure it; do not force it if it resists.
Many automatic watches can also be wound by hand. With the watch off your wrist, turn the crown in the winding direction using gentle, steady motions. The correct direction and recommended number of turns can vary, so check the owner’s manual. Stop if the crown feels gritty, catches, or requires unusual force.
Consider Wear and Storage
An automatic watch winds as your wrist moves, but a short or quiet day may not provide enough motion to keep it running. If the watch has been unworn for a day or more, it may have used up its stored power. After winding it according to the manual, wear it through your normal routine and see whether it continues to run.
Think about where and how the watch was stored. A watch left unused may simply need winding, while exposure to a strong impact, moisture, or extreme conditions can point to a problem. Keep it away from magnets and avoid testing it near magnetic clasps or speakers if its accuracy changed suddenly. Don’t shake it vigorously to restart it.
Notice Symptoms Without Forcing
After a gentle wind, observe whether the seconds hand moves and whether the watch keeps running. Note if it stops again quickly, runs noticeably fast or slow, or has a crown that will not turn smoothly. These details can help a watchmaker narrow down the issue. If the watch has a power reserve indicator, check it as described in the manual.
Do not open the case or apply oil at home. The movement contains small parts that can be damaged by dust, incorrect tools, or excess lubricant. If you see moisture under the crystal, hear a new rattle, or notice damage after a drop, stop wearing the watch and arrange an inspection.
Know When to Get Help
Seek professional diagnosis if the watch will not start after the manufacturer’s winding instructions, repeatedly stops despite regular wear, or shows a sudden change in accuracy. A watchmaker can inspect the movement and check for issues such as dried lubricant, wear, or damage without relying on guesswork. Service needs depend on the model, condition, and symptoms.
Before bringing it in, write down when the watch stops, how long it runs after winding, and any recent impact or water exposure. Bring the watch and its manual if available. James River Watchworks in Richmond can assess an automatic watch; contact the shop to ask about inspection arrangements.
A stopped automatic watch may only need winding after time off your wrist. Check the crown, follow the manual, and observe how it runs without forcing the mechanism. If it still stops or behaves differently, a watchmaker can identify the cause and recommend a suitable next step. Contact a local watch repair shop to arrange an assessment.
