Everything that James has said about the Sony applies to any Android watch.
Whichever watch you choose:
1. It must be running Android Wear 2.0.
2. It must have wifi.
3. You must have the Google Play Store on the watch.
If you do not have the Play Store on your watch, it's probably not a watch that is running Android Wear 2.0. However, we cannot and have not tested every watch.
According to a web search, it looks like the Huawei 2 Classic is running Android Wear 2.0 and has wifi. It may be OK.
