Can I changes watch faces using a windows computer?

[home_pcc]

Hello, I apologise if thsi has already been discussed. I just ordered an LG Urbane. Unfortunately I have an Iphone. I understand that I can use Andriod Wear to interact with my watch, but I also understand that I cant install 3 Third party watch faces on it using Andriod Wear with my iphone. I was wondering if there is ANY way to install 3 Third party watches faces on my LG Urbane using my windows computer or my iphone. I dont care how complicated it is.

Any help would be apprciated.
Thanks
