Trochę mnie to zaciekawiło i szperając w necie trafiłem na taki wpis na WUS: „I just had my PO serviced and had a new crystal installed. The old crystal had about a hundred scratches in the AR coating visible in any and all light and it drove me nuts. All of the exterior AR coatings on all of my high end watches have marks, and my 18 year old Rolex which has no exterior coating doesn't have a mark on it. Needless to say I was very happy when I emailed Omega with regards to my new crystal and they replied with: "Please be advised that the original crystal made use of anti-reflecting coating on both the inside and outside. However, this has since been changed in order to avoid scratching of the exterior coating leading to an unpleasant appearance of the crystal. Therefore, we are now coating the interior of the crystal only." I don't know if they mean ALL of their crystals on all of their models are done this way now, but I know for sure the Planet Oceans are interior only. I was happy to see this and thought I'd share. I hope more companies decide to do this. Tom” Link do wątku: http://forums.watchuseek.com/f20/ar-coating-planet-ocean-1886218-3.html#/topics/1886218?page=1
