Hmmm... Sapphy crystal with tool matte dial. A fantastic combination if you ask me!
Definitely as alligoat suggested- TW Best case, matte dial, gen insert, match lume the hands, add a vintage 3035 'style' (i.e. fonts) datewheel, gen crown/tube, drill the lugs, get a hollow link loose end bracelet and I think you're pretty much set!
I'd suggest using a gen datewheel from a 3035, except the date rotates in the wrong direction still (CCW).
