Symptoms
- Screen stays black no matter what button is pressed
- No response even when placed on the charger
- Watch was working fine and then went dark
- Watch shows a logo but never finishes starting
Likely causes
- CommonBattery fully dischargedA watch left uncharged for an extended period can appear completely dead.
- CommonCharger not making contactA watch that's actually just not charging looks identical to one that's off.
- PossibleSoftware freeze during startupA stuck update or corrupted process can prevent the screen from lighting up.
- Less commonHardware failure of the display or batteryAfter significant age or damage, internal components can fail outright.
What to do
- Place the watch on its charger and leave it for at least 30 minutes before assuming it's dead.
- Clean the charging contacts on both the watch and charger, and confirm the charger is plugged into a working power source.
- Try a different cable or wall adapter if available.
- Attempt a forced restart using the button combination for your specific watch model (usually holding the side or crown button for 10–15 seconds).
- Look for any sign of life, such as a charging icon, vibration, or logo, which tells you it's a software rather than power issue.
- If the watch shows a logo but hangs there repeatedly, look up the force-reset or recovery mode steps for that exact model.
When to call a pro
If the watch shows absolutely no response after an extended charge, a cable swap, and a forced restart attempt, it likely needs professional diagnosis for a battery or board failure.
