For the most part, Google has issued an update to the Pixel Watch roughly once a month. Most were simple security updates, while others included new features and OS upgrades. Fans expected an update in October, but Google delayed it until this month. This update will resume the rollout of Wear OS 5 to Pixel Watch 1 and Pixel Watch 2 users after a series of crashes caused Google to pause it back in September. After several months of work, the company has addressed the cause of the crashes and is confident that yesterday's update will be stable.
In addition to Wear OS 5, the update will also include better camera controls and changes to the Pixel Recorder app, which will be available through the Play Store. Your individual watch will notify you when the update is available for download, so you don't have to constantly check for it. The first update for the Pixel Watch 3 since its launch is also coming with bug fixes and security updates. All Pixel Watch models will eventually update to version AW2A.241105.012, although when the update happens will depend on both the carrier and the device.
