Condensation can build up inside a watch that is exposed to water or extreme humidity. This is a guide about removing condensation from inside a watch.
How can i remove condensation from inside a watch?

Not sure if this will work but... I know that if you drop your cell phone in water and put it in a jar of rice (uncooked), the rice draws the moisture out of the phone. I've done it and it worked. You might try it with your watch.
Try leaving it on a sunny window sill for a few hours.
You need to take off the back of the watch (either screw or pry off) then remove the inner workings, if possible. Place everything under a lamp so the heat evaporates all moisture. Leave as long as needed. If you don't open the watch up, the moisture will rust the inner workings. Hope this helps. I actually do this at work as I work in a jewellery shop.
To protect the watch, wrap it loosely in a thin scrap of cotton cloth (a handkerchief works well). Then place it on a layer of silica gel (used for drying flowers - available in craft stores) and add a layer of silica gel on top. Leave it for a day or two and all moisture will be absorbed.
I bought a watch not realizing it was not water resistant. It got wet and now has condensation on the glass. How do I get rid of the condensation?

If you can pop the back off, do it and let it air dry. I've done this more than once. lol
I had the this problem and was told by someone in a jewelry dept. to take the back off and let it air dry for a few days. It worked!!!
You could always place it above a reading lamp, or for that matter any lamp in the house and in a few hours the head from the lamp will dry it out.
Manila, Philippines: the rice solution works. I couldn't get the back off the watch. In the absence of any watch repair shops in the area, I put the watch in rice in a bag and left it in the sunlight for 24 hours. Result, no more condensation in the watch. Thanks for the suggestion.
