My Apple Watch only shows the time?

Hi Bently2,

Thanks for reaching out to the community. If you Apple Watch is only displaying the time in green, you will need to charge it. Take a look at the steps and article below for charging your Apple Watch.

1. "In a well-ventilated area, place your charger or charging cable on a flat surface. Your Apple Watch comes with the Apple Watch Magnetic Fast Charger to USB-C Cable (Apple Watch Series 7 and Apple Watch Series 8 only) or the Apple Watch Magnetic Charging Cable (other models). You can also use a MagSafe Duo Charger or Apple Watch Magnetic Charging Dock (sold separately).
2. Plug the charging cable into the power adapter.
3. Plug the adapter into a power outlet".
