Overview
- The October rollout for Pixel Watch 1 arrives as build BW1A.251005.003.W1 for both LTE and Bluetooth/Wi‑Fi models.
- The update keeps the watch on Android 15 with Wear OS 5.1 rather than moving to Wear OS 6 and Android 16.
- Google has not explicitly said updates are ending, though its published schedule lists support for the original model only through October 2025.
- Google’s watch policy promises three years of updates starting when a device first became available on the Google Store in the US.
- Users can check for the build via Settings > System > System updates on the watch, with a reported tapping trick sometimes prompting the download.
