Hello. I have an old-fashioned wristwatch, which I inadvertently kept on in the shower and before it was too late, it got water in it. Have tried using a hairdryer to get it out, but no luck. Any tips?
Take it to a jeweller's. They have the expertise to open it up and dry its innards. Once you've got water in the watch, no matter how many times it seems to be dry, condensation will occur intermittently on the glass. They'll probably only charge you a tenner.
