This should not be a problem with the right applications.

"To use the Galaxy Watch on your Samsung phone, all you need to do is download and install the Galaxy Wearable app from the Google Play Store, also known as Samsung Gear. The application provides all the information about the watch and also acts as an advanced manager that personalises the functions of the accessory. However, if you install the Galaxy Wearable application on a Huawei smartphone, you will need to install an additional Galaxy Watch Plugin application. Thanks to the second application, your smartphone can easily synchronise the data with the accessory and provide, for example, information from the calendar or the exact location. After installing the Galaxy Watch Plugin, your Samsung Smart Watch will work on your Huawei phone as effectively as on any Samsung smartphone."
