Saint George (or saint Michael?) and the Dragon

My dad recently sent me this picture. He took it at the Roskilde Cathedral in Denmark, which we visited thirty years ago or so. This is a 800 year old clock, still working. Or at least it was working when we visited it. I barely remembered seeing this ancient clock. You can see on it a depiction of Saint George or Saint Michael killing the Dragon. We are not sure: researches we made gave us contradictory information. My money is on saint George as I think you can see a princess somewhere and he's on horseback. If I am right, then we saw in Denmark a dramatic representation on a clock of the single most famous exploit of the patron saint of Englishmen. I thought about sharing the picture for Saint George's Day, but I could not wait. I want to know if it is Saint George or Saint Michael, for one and thought I would ask it here. I also thought that either way, a 800 year old clock with a dramatic depiction of a fight against a dragon is just too cool not to share as soon as possible. So here it is.
