I have a V4 bracelet and have soaked, washed, and oiled the bracelet with no issues. I live in Florida by the beaches. Hard pressed to find more humid conditions then my backyard. I'd follow the above suggestions to take care of the issue.
I am equally as surprised. I'm anxiously waiting. While I do love the classic submariner there is still something special about the ceramic bezel. I'm interested in a TT if they ever produce that. I think the TT look elegant with the new lug thickness. I may be alone in that thought lol.
