Michael,
My 2998 has almost the identical hand corrosion, and I have it also on a Submariner. In your opinion, is it something in the way the Tritium reacts with the plating, or just the plating’s exposure to moisture over a long period of time?
I think it the radium in the hands might have caused light surface corrosion maybe. I have had trench watches before with very fragile hands that are easy to break and believe it was some kind of reaction to the radium, I could be wrong though.
Regarding moisture ingress, it could be but in minute amounts, I have worn this watch in the worse Yorkshire weather and it has never steamed up, the movement is in spectacular condition and doesn’t show any signs of moisture that I can see.
