WD40 and bezel?

[lavaman]

My bezel on my GMT II has suddenly become very stiff. I ran it under gentle tap water (without working the bezel), which seemed to help. No, I wasn't at the beach...

Q: a drop or two of wd-40, good idea, bad idea?

The watch didnt leave my wrist from the time it was working normally and the time it suddenly started acting goofy, so no sand, no drop, shock or anything else to explain.

and it's still running fine

suggestions to get the bezel moving (no, i haven't tried to force it, obviously)

thanks!
