Thanks for your posting.

My best advice in this situation is to have the watch assessed by an expert. We have seen too many stories here of amazing watches that were damaged or ruined by local jewelry stores that were trying to do good things for their customers, but lacked the know-how to handle a difficult / complicated assignments. Also, depending which model you have, the dust may be radium, which will require some special handling.

Send or post photos if you are so inclined . . . it would be good to see this one.

: If it's dirt, cleaning it can be easy or at least possible. If it
: is corrosion, or dirt which has turned into corrosion it will be
: more difficult or impossible. The problem with dial cleaning is
: that it can be difficult to tell the difference before you ruin
: the dial.
