Hi there So I found out the hard way that the crystal on the Tag Carrera 1887 which is "scratch resistant" according to TAG is an accurate statement.. But the caveat to that is the anti-glare coating on the face of it is quite prone to scuffs apparently which I have found out the hard way . Anyway - Before joining these forums I looked into how to correct this issue. I brought it to a local watch maker and he said well, you didn't scuff the crystal at all, but you scuffed the anti glare coating on the face of it. His recommendation obviously was a new crystal, but to replace that you have to take the whole watch apart I was told. So I looked into how to fix this on my own if possible and found that diamond lapping pastes usually do the trick to removing scratches from crystal, even saphire, so I figured this would be great for just a scuff to the anti-glare. Anyway.. I did it last night and the Polish in me led me to a small box where I taped where now it doesn't have the anti-glare coating.. lol. The original area I tried to fix is 90% gone, so I think with a bit more elbow grease I could eliminate it completely. So at this point I'm considering, well actually I think it's the only option... to do the entire face and remove the anti-glare coating since having a small box in the center where its gone because it looks weird. Has anyone else done this? Rather than me buffing off the coating is there something that would remove it quicker? Paint thinner? I will prob call Tag today and ask.
