Hello Guy,
This question keeps getting sent to me in private emails over and over again, and keeps coming back.
For that reason I would like to answer it now once and for all online in the hope it can be put to rest ;-)
1. No coatings can be polished;
2. I repeat: no coatings can be polished;
3. Scratched DLC, PVD, or TITALYT is very expensive to repair as the entire bezel must be bead-blasted back to the metal and be re-coated or the bezel replaced;
4. We do not sell or promote these coatings for their scratch resistance;
5. Even the sleeve of a shirt made of the finest Egyptian cotton will still produce surface scratches on all types of gold - however careful you are;
6. These surface coatings mentioned above in point 3 will help only with resisting those types of light surface scratches;
7. No coating can resist dings very well, since the metal below the coating still can get dented;
8. The difference in surface scratch resistance between TITALYT and everything else is minimal to the point of being negligible;
9. See again point 4 above.
In actual fact, for all these reasons, RMW plans to drop various coatings in the very near future, because they seem to give owners the idea that their watches have become 'indestructible' by being coated, having taken on protective super-powers ;-) !
Hope this helps,
