What are the main differences between these movements? Are the dimensions the same?

I believe all is the same except that the 51112 used in the Jumbo Ingenieur has the added feature of a gold weight on the oscillator mass. That is, the rotor has the gold Probus Scafusia seal since there is a see-through back.
