In the United States, after the California Right to Repair Act landed in effect, Google recently confirmed to The Verge media, that the user’s Pixel Watch screen once broken, at this stage can not provide repair services.

A Google spokesperson said, “At this time, we do not have any repair options for Google Pixel Watch Watches. After your watch encounters damage, you can contact Google Pixel Watch customer service to check for replacement options.”
The Google Store does not offer an extended warranty option for Pixel Watch Watches, and once a user’s watch screen is accidentally damaged, there will be no official screen replacement repair option.
iFixit said in its disassembly of the Pixel Watch that although it is difficult to replace the screen, it is completely repairable from a technical point of view, and provided a tutorial on how to replace the cracked and broken screen.
