Bootloader Unlock
The bootloader of the Pixel Watch 3 can be unlocked by enabling “OEM unlock” within the Android developer options, rebooting into bootloader mode via ADB and unlocking afterward via fastboot.
# reboot to bootloader
adb reboot bootloader
# check if the watch is unlockable. If yes it returns "1"
fastboot flashing get_unlock_ability
# ask the device to prompt for bootloader unlock
fastboot flashing unlock
After issuing the unlock command, the action must be confirmed on the watch.
Fastboot
You can reach Fastboot Mode without pairing the device by tapping the upper left and lower right of the display right after booting (the first Google Logo). See also here.
Repair
The Pixel Watch 3 has replaceable straps, but the device is glued shut, making repair attempts harder.
Firmware
OTA firmware images are available on developers.google.com. The zip files contain a file called payload.bin that can be extracted with payload-dumper-go.
Once extracted, the partitions are contained in named image files. e.g. boot.img.
