Google began rolling out the May 2024 security update for the original Pixel Watch and Pixel Watch 2 on May 6. It brings the May 5, 2024 security patch in build TWD9.240505.001.A1, based on Wear OS 4. The rollout began in 2024; it is not a current update.

Which Pixel Watches received the update?

The release covered the original Google Pixel Watch and Pixel Watch 2, including Wi-Fi and LTE variants where applicable. Contemporary coverage reported the same build for four model variants. This was a Pixel Watch update, not a release for every Wear OS watch. Availability could vary during the staged rollout, including by region or carrier.

What does the May 2024 update include?

The package uses build TWD9.240505.001.A1, runs on Wear OS 4, and sets the Android security update level to May 5, 2024. Google began the rollout on May 6; the patch date is not the date every owner received the over-the-air update.

The published changelog identified a monthly security update, but did not list major user-facing features or specific bug fixes. It was a quiet security-focused release, not a Feature Drop. The available launch coverage does not enumerate individual vulnerabilities or confirm changes to battery life, performance, health tracking, or connectivity. 9to5Google’s May 2024 update coverage and an independent contemporary report describe the limited release.

  • The new Google Pixel Watch 5 offers a smarter way to a healthier you.[1,2]; Designed for Gemini Intelligence, get proactive help, and personalized insights from Google Health[3,4]; watch is compatible with Android devices only; not compatible with iOS devices
  • Precision-crafted to do it all: The Google Pixel Watch 5 features the domed Actua 360 display with scratch-resistant Gorilla Glass and up to 40 hours of battery life[1,5]

  • Detects loss of pulse, then calls for help: Pixel Watch 5 is the only smartwatch to feature Loss of Pulse Detection, which can prompt a call to emergency services[10]

How to check for and install the update

  1. On the watch, open Settings.
  2. Scroll to System, then tap System updates.
  3. If the update is offered, follow the on-screen instructions and let installation finish.
  4. Keep the watch adequately charged; placing it on its charger before updating is a sensible precaution.

The rollout was staged, so not seeing the update immediately did not mean the watch was unsupported. Retry later rather than treating the rollout start date as a promise of immediate availability. The normal check path and release details were reported by Android Headlines.

If the update does not appear

Try the normal checks first

  • Confirm the watch has Wi-Fi access and adequate battery, then check again later.
  • Restart the watch and retry the update check.
  • Check that the paired phone and Pixel Watch app are up to date.

Reported update-check workarounds

One unofficially reported tactic is to open Settings > System > System updates, wait for “Your watch is up to date,” then tap the watch/checkmark icon repeatedly and wait to see whether a download starts. This is a reported workaround, not a Google-guaranteed procedure; it may not work for every watch. 9to5Google previously described the repeated-tap method.

Another reported, optional tactic is to go to Settings > Connectivity and temporarily turn Bluetooth off so the watch uses Wi-Fi for downloading. This is not required, and it can interrupt the watch’s phone connection while Bluetooth is disabled. Both tactics were also noted in contemporary coverage of the May release.

Manual installation is an advanced alternative

Google provides full OTA images for Pixel Watch devices on its official Pixel Watch OTA page. Manual installation is unnecessary for most owners, and the exact image must match the device variant. Google’s page sets out terms and restrictions; use it only if you understand the risks and follow the instructions there. Do not sideload an image simply because an over-the-air update has not appeared yet.

How to verify the installed version

After installation, check the watch’s software information and compare it with the release identifiers: build TWD9.240505.001.A1, Wear OS 4, and Android security update level May 5, 2024. If the watch still reports an older build, it has not installed this particular release.
