Hello all, I bought a pre loved W series 14060 sub last year but had dust appear under the crystal. Got in contact with the jeweller I bought it from and they serviced it for free to get rid so happy with that. I was just wondering how often I will need to send it off to get this removed? I have seen a thread on this forum about a guy who relumes in any colour you want, including aged tritium which looks awesome. I'm not sure whether to get this done or leave it to patina on its own, I can't really put up with dust in it, it's very distracting in the sun. Advice please. Thanks all in advance.
