Can someone please tell me what program I use to create these watch faces

Can someone please tell me what program I use to create these watch faces for android (not wear) the Chinese ones! I know there’s loads out there to download but I’d like a go myself. Thanks.

You can use ClockSkinMaker. It’s very easy to use.

Or the very cool WFD : http://roundandroidwatches.proboards.com/post/14193/thread
