Dear All friends & gurus,

I've noticed that in a couple of years, the tritium dust on my 5513 dial have started to corroded the dial causing the dial and/or dust become a black spot. Do any body experienced this before and is there any way to prevent it getting worsen... maybe by cleaning the dust away. I m planning to used a tiny rodico paste and try to extract the dust very slowly one by one dust at a time.. I know I will spend hours/days to do this, but if it can be done I am willing to do it. Have tried to bring to my watchmaker but seems they hesitate to do anything to it.

I noticed from this forum several dealers selling their very clean 5513 without any tritium dust around the pot. Is this because they did clean it or is it really exist that after 40 years some dial still contain no dust? This make me wonder all the time. Should I go ahead try to do this project or have to live with this corroded dust.

Many thanks in advance for all the advice.

Luckyl

and after Rodico...

Since There are no responses.. I try to put some guts to deal the dust with Rodico.. Using a toothpick and wrap the rodico to the end of the tip, gently push down and up, the rodico doest his works.. Not all can be extracted and I think I have get rid around 30% of the dust.. Sometimes even touch the lume pot and the lettering but they hold to the dial quite strong..

Here are the result after works.. Some dirt are from the glasses.
Cheers..

I think the main culprit here was moisture ingress..

..reacting and adding to the lume delaminating issue.. However your effort has made a big difference..

Yes, tough process with a lot of risk

Doing something similar with an extreme Silver Print Tudor dial. Rodico, Peg Wood, and these Nail Sponges were very helpful (see link)

Early treatment will actually save the dial

I think if we take some guts and deal with this dust earlier stage, we might save the dial from being corroded into a black stain. It is when we are too scared to do something and watching the dial getting worse time to time, then it is too late. Earlier tritium dust is quite easy to take off, it is those old dust that maybe reacted with moisture become sticky and stick to the dial. I can't get rid of those ones.

Anyway I m happy with the result and enjoying a better cleaner dial.
