Crystal Sapphire - Can this be fixed

[Feb_29]

So, a casing from 45 ACP landed on the top of my 116710BLNR, making barley visible chip on the sapphire crystal(circled on the pic). I've searched, if this can be fixed but found only chipped crystal on the edge of the crystal, not like in my case. Also, asked other people and they said crystal cannot be fix, only acrylic can. My AD said the same and advise to send watch to RSC for new crystal replacement. My watch is still under Rolex warranty. However, AD said Rolex will not replace with new one for free, they will charge full price for it(about $300). I can live with this until first service interwall, doesn't bother me much. But if this can be fixed some how I'd like to give it a try. Appreciate your input guys.
