Advise needed - Sea-Dweller got sprayed with paint

[Jhquek]

Hey All, Got a bit of tiny issue.

My Dads watch 16600 Sea Dweller got sprayed with speckles of ship external coating paint, apparently he used his watch hand to shield his face while walking past some workers coating a ship's external.

Washing with toothbrush removed some speckles but there's paint still.
On the bezel, crystal, case and bracelet.

Bracelet should be easy fix but any idea on bezel and crystal.

Any DIY suggestions?
Going to RSC probably gets a recommendation of re-polish, replacement of bezel insert and crystal.
