The retaining ring is just like any other 16610 ring - you need to get a thin flat blade under it and work round it, prising it up. It’s tight and probably very well seated, so you might have to start off tapping a razor blade in between the case and ring.
The bezel is fun to reassemble - if you disassembled it correctly then it should be quite easy to understand the principle, but maybe you managed to force it off without removing the wire circlip first? (Although I’ve never managed to do that - I have bent two bezels while trying though). Anyway, to reassemble I find the best thing to do is bend the long click spring into position inside the bezel, and then place the spring/bezel assembly in position, relocating the end of the click spring in its hole. Then, the bezel is secured in place by feeding/bending/clipping the circlip back into its location in its grooves under the retaining ring and in the bezel.
There’s probably a pictorial guide on here somewhere… because a picture paints a thousand words and my rambling explanation may not have helped much… I had a quick search but couldn’t find one. But I know I posted some pics myself somewhere, when I bent my BP bluesie bezel.
Good luck!
