Looks like your gasket is in the correct position, from what I remember when I removed mine.
If you have a press and are very careful (plus you might need to modify your die to accommodate the cyclops), you can use that to push it in.
In my case, I didn't need a press or die. I pushed the bezel in while rotating the bezel on the case and it slid in (I watched a video where someone else did that). Worked perfectly for me. I tried pulling it out with my fingers too and it didn't budge.
