Weiss didn't fight the original version of the armor. She said she saw versions of it in a room, I assume the two we saw on either sides of the stairs in the Schnee manor.

The Geist-possessed armor that Weiss fought in the manga and the White Trailer is 3 times stronger than those suits of armor in their normal, not-possessed state.
