Yeah it's the wrong crown and the dial is not the right one but then they did many versions of the same watch and they don't have them all in the data base.
The crown looks more like the one for my 1949 watch. You can get a new one for that case but it will cost $30-40.
Here you can see the Omega I have with some other watches.
As you can see the dial and hands don't match up with the picture but they match the info text.
