Specification Sheet

Keep the Wear OS by Google app running in the foreground and avoid
performing any other operations on your phone when pairing your watch
through the Wear OS by Google app. When the message Touch "Done" on
your phone appears on the watch, touch Done on the phone to complete
the pairing process.
If pairing is taking too long, or the message Getting watch details stays on
the screen, try the following steps to see if the issue is resolved:
1. Reset the watch to factory settings. If pairing fails or the message Getting
watch details stays on the screen for too long, touch and hold the power
button on the watch (the button on the top right side of the watch) then go
to Settings > System > and touch Disconnect & reset to restore the watch
to factory settings.
2. If the watch has previously been paired with a phone, reset the watch to
factory settings and then pair with the new phone. If you are using an
iPhone, you need to unpair the watch from the phone before performing a
factory reset. Go to Settings > Bluetooth on your phone, then touch the info
icon next to the watch's Bluetooth name and touch Forget this Device. After
this, turn Bluetooth off and then on again on the phone, exit and restart the
Wear OS by Google app, and then re-pair the watch with the phone.
