As of this writing, the August 2025 update for the Galaxy Watch 8, Watch 8 Classic, and Watch Ultra is available in Samsung’s home country of South Korea. The OTA packages weigh around 160MB, with the exact download sizes varying depending on the model and connectivity variant. The new firmware build numbers are as follows:

Samsung will soon roll out these updates globally. If you own any of its latest wearables, head over to the Galaxy Wearable app on your connected smartphone to check for updates. If the new firmware release has already hit your unit, you will see an “Update” button right below your watch’s name on the app’s home page. You can also manually check for updates by going to Watch settings > Watch software update > Download and install.

Even though this patch doesn’t add flashy new features, it’s an important step in keeping your wearable secure, smooth, and ready for future upgrades. So, you should install the new patch as soon as it becomes available for your Galaxy Watch 8, Watch 8 Classic, or Watch Ultra.
