I read somewhere the AP white ceramic has a higher hardness rating then the black ceramic is this just a byproduct of the composite change required for the different colour?

I thought ceramic watches were scratch proof.....

Well, I was suggesting starting with a pencil eraser to aid in rubbing off any transfer residue, if that’s all there is. Brasso would scare me not because of what it would do to the ceramic, but what a liquid abrasive would do the metal parts if it ran away at all. I’m sure it can be controlled, but again, I would first try less abrasive solutions. But that’s just my cautious nature. |

Thanks - very interesting. This is what I was referring to about different types of ceramic, as they are not all created equal. I am hypothesising, but would assume manufacturing specifics such as time, pressure, heat as well as the exact ‘recipe’ formulation would all have an impact on colour and hardness. For my ceramic kitchen knives from Kyocera, their black ceramic I believe is harder than their white ceramic. So colour isn’t necessarily an indicator of hardness. I don’t know if they also include other trace elements or compounds to control colour or if it’s just the natural colour of the base powder they use. An interesting area for sure !

Just so you know I scratched the ceramic bezel on my 44 within 6 months of buying it. Like you I thought the ceramic couldn’t be damaged, not easily anyway. The new bezel cost £2200. Sent from my iPhone using Tapatalk |

On the topic of scratching I haven’t been able to acquires a scratch like the one in this thread but I have a few small chips on my ceramic bezel. So my experience is that the ceramic is scratch proof but brittle.

Various additional materials are added to improve certain attributes, one of the principle ones being opacity, thereby enhancing the gloss level. Matting is done as a post-process rather than trying to produce a matte product straight from the mould. You’re fine, everyone is prone to the odd Freudian slip. |

Yikes! Would you mind sharing some pictures of that? I suppose it’s much the same as stainless steel or gold in this case, though maybe the chips are fewer and lesser.

Where does the black or white colour come from - is it from the compound going in, the process applied or something else ?

If it needs replacing, I will do it later on. No need now as I can hardly see them - I have to gawp and catch them in the right light etc. To replace for just those would be a waste of money. |

Even if they were scratches, I am surprised that they cant polish / brush them out....
A little self defeating I would say. |

Good luck getting scratches off. You might want to consider another explanation for your wife though....

So I had a small mark on my ceramic bezel of my FC Diver, which just came back from service and APSC didn't even mention it or the replacement and I wasnt going to fix it anyhow. After reading this thread, I decided to try one of the ink erasers on the mark and guess what? It worked! Before and after photos below and link to the eraser I ordered on Amazon.

Excellent. Thank you V25V - I have ordered the eraser ! BTW thats a lovely diver you have there.
How much pressure did you apply? Assume you worked with the brushed grain on the bezel? |

I thought ceramic watches were scratch proof.....

I was very gentle with it but based on what PJ has said, which makes sense on the strength of ceramic, I dont think you will do any damage pressing hard. But yes, with the grain and just took my time. Slowly started going away and after several passes and washes in between, gone! Sent from my iPhone using Tapatalk Pro |

I was little hesitant on brasso as well, then I saw the other thread and decided to give it a try. Now the bezel is flawless
