At first look, my thought was that you just practicing use of that diver extension on your sweater instead of proper diver suit !
Anyway, in my case, same watch, same source (no pics, sorry!). Not same problems.
My piece is with centered pearl and aligned crystal/cyclop date window.
But in my case, the bezel insert was not properly aligned with dial markings .
Not so easy job to fix it. But after short messing with sharp knife I managed to took complete bezel off , pop insert out and realigned it (just couple of drops of the glue).
Regarding pearl, I think that it is just glued on the insert. Maybe is worth to carefully remove pearl (with a little help of heat from hairdryer) and then just re-glue it properly. Just my 2 cents!
Rotating the crystal - not an easy job for the average Joe. Just my opinion.
For crown/guards look at this gen LV Sub:
Dont spend to much time looking on that watch - wear it!
