Started by giving the case a clean, then polished the sides to remove some hairlines, and redid the brushed style finish on the top surfaces with some 600grit wet and dry glued to a nail file. (which hasn't been missed yet). Then cleaned the case again.
Pressing the Domed sapphire in with my new (cheap) press.
Case with Domed Sapphire and new polished chapter ring in place. Re-used the crystal seal as it's not going to see use underwater anymore and the old one is good enough for a dust seal I think. Hopefully it's seated far enough in!
