Lost Android Wear devices must also be running Android Wear 2.0 and up.

Remotely find, lock, or erase
When Find My Device connects with a device, you see the device’s location, and the device gets a notification.

Open android find device and sign in to your Google Account.
If you have more than one device, click the lost device at the top of the screen.
On the map, see about where the device is.
The location is approximate and may not be accurate.
If your device can’t be found, Find My Device will show its last known location, if available.
Pick what you want to do. If needed, first click Enable lock & erase.
Play sound
Rings your device at full volume for 5 minutes, even if it’s set to silent or vibrate.

Erase
