Where I live the young kids play softball and soccer, high school and beyond.....rugby (your style). We used to have a high school football time but it disappeared long ago with the surge in popularity of rugby.
Now back to that watch and 5-a-side. It's driving me crazy that I found a link about 5-a-side with notations under the hit about 1911 and a Cup. But darn it, when I hit the link I just get a whole list of other links and have yet to find the one that speaks about that elusive Cup.
