I'm not sure I understand your comment about blading the watermark image. I know how to blade, though. I have done that to trim clips.
Assumiing your watermark is one long clip and you want to rotate the logo (or watermark).
You said in your first post that you know how to do the animation ("I know how to rotate something once"). Well, assuming that rotation takes five seconds to complete (finishing up in the same position it started) then all you need to do is replicate that rotation throughout the timeline, to get your repeats.
You can make the logo clip the same length as the rotation, copy the clip and then keep applying it to the timeline - or you could cut the (full length) clip with the blade, every five seconds, copy the first clip (the one with the rotation on it) and then select all the other logo clips and press Option+Cmd+V to paste the effects - so that all the clips will have exactly the same attributes as the original clip (includes all other settings too).
