The Google Pixel Watch has been notoriously difficult to repair. Instead of officially committing to repairs, Google previously resorted to replacing any broken or malfunctioning Pixel Watch, forcing experts to look for workarounds. However, it is now course-correcting with the newly announced Pixel Watch 4 and making it the first serviceable watch to have launched under the Pixel lineup.
While announcing the Pixel Watch 4, Google has confirmed it will offer services for repairing the display or the battery. However, the details about repairing other parts, such as the rotating crown or other internal components, haven’t been mentioned.
