Is this Series 2 repairable? Just a gasket replacement?

Hi, I was in Seattle taking a nice hot shower when my watch face just came off. It was attached by the cables and all, but the face just fell off.. Watching some videos, seems like it's a simple gasket replacement, but the back of the face looks like it's missing part of the rim?

Is the rim stuck on the apple watch body? Really confused right now, as the ifixit video shows the back of the face having an extra rim. When you look at the orange part of the face, the video shows a little extra rim.
