If the charging indicator (lightning bolt) is not visible, the charger does not detect the watch. Try the following tips:
- Reseat the watch on the charger.
- Make sure the charger pins align with the caseback grooves.
- Verify watch is seated snugly on charger with no gap.
- Verify nothing is between charger and device, i.e. no dust, tape, etc.
- Make sure the charger is getting power.
- Try changing the charger power source, i.e. move to wall outlet from laptop.
