Hello ginarr,

Thanks for posting in the Apple Support Communities.

It sounds like you're looking to install watchOS 6.3 on your Apple Watch, right?

If we have that correct, be sure to keep your Apple Watch connected to the charger and near your iPhone while updating. For assistance with updating, check out the steps below. You can find additional details here: Update Apple Watch software - Apple Support

Check for and install software updates

1. Open the Apple Watch app on your iPhone.

2. Tap My Watch, go to General > Software Update, then, if an update is available, tap Download and Install.

If that isn't helpful, contact Apple Support directly for additional assistance.

Have a great day!
