If you are selling your Android Wear smartwatch or just want to start off with a fresh slate, users are now able to perform a factory master reset on their smartwatches quickly.
After waking the smartwatch, hold the power button until you get the device options like power on/off. Alternatively, you can scroll to the settings menu by double tapping on display, or say “OK Google” followed by “settings” if you prefer voice controls.
Inside settings, scroll to find the “reset device” option and tap on it. You will be required to authenticate your selection of the reset option, which is your last chance to back out. Once confirmed, the reset begins, and the device will power cycle. Once this is done, you will be able to proceed with a fresh setup.
