Bootloader unlock

To begin using the device you unfortunately need to set it up through the Google Pixel Watch app on a full fat Android 9+ device over Bluetooth. The charging base and the pogo pins on the watch back side are USB data transfer enabled. Then enable developer mode, allow OEM unlocking and fastboot flashing unlock (flashing anything from https://developers.google.com/android/images-watch also allows to keep unlocked bootloader)

How to enter flash mode

To enter fastboot tap (or more likely spam) top-left and bottom-right corners of the circular display as the device boots. Example video explaining the whole process: https://www.youtube.com/watch?v=B5F3ozJPWLg
