HUAWEI Watch USA -> Europe

Hi guys, I have a Huawei Watch bought in USA, but now i'm in Germany and when I ask for the weather, the clock shows it to Fahrenheit. BUT i want to see the weather in Celsius. And also the clock sometimes shows the storm warning in America. But i don't need it.

Do you have any solution for my problem ?

Or may be I can change the android wear or huawei watch firmware from the usa to the europe version?
Thank you
