watch keeps getting condensation in it?

have a cheap watch and a Tissot and both have same problem with condensation? I actually taken the cheap watch apart and dried it and put it together?

It has been super hot and muggy out so i'm not sure if it's just the heat? any suggestions.

Don't buy cheap watches.
And buy a thesarus dictionary to assertain the differnce between Jewelry and watches. Their is a 'Watches' section in this forum.
