The Samsung Galaxy Watch is not only made of mechanical parts, it also has wires, processors, data chips, and software. As with other smart devices, the software and apps on the watch will need to be updated from time to time. However, you can update with the watch or phone whether you have a phone or not.
Update the software on your watch
When your phone and watch are connected, you can use the Galaxy Wearable app to regularly check for updates. Or, if you initially set up your watch without a phone, you can apply updates from the watch itself.
Update watch software with an Android phone
1. Make sure the watch has a good charge on it before starting the update process. You may not be able to update without at least a 30% charge.
2. On the connected phone, navigate to and open the Galaxy Wearable app.
3. Tap Watch settings, and then tap Watch software update. Tap Download and install.

4. While the software update is being installed, the watch will restart.
You can also update a watch directly from the watch. It will still need to be paired to a compatible Android phone. Just open Settings, scroll down to and then tap Software update.
Or, to check for the latest software update please follow the below steps:
Connect your Samsung Galaxy Watch 6 to your paired smartphone.
Open the Galaxy Wearable app on your smartphone.
Navigate to "Watch software update" or a similar option within the app.
Check for available updates. If there's a new update, you should be able to download and install it directly from the app.
