How I can take pride watchface in Russia

Hard to say. According to the Keynote for WWDC, it was supposed to become available after 12:00 noon, PDT. It is supposed to be available through the Watch app on the iPhone, when you go to the Face Gallery. I just opened mine, and it appears under New in watchOS.

Or it may be something that is rolling out in groups, and has not made it there yet. I would wait and see what happens, but give it some time.

Make sure that your phone is updated to iOS 11.4, and your Watch is on watchOS 4.3.1.
