I took my watch to the jewelry counter at Target and had them put the case back together the same way they do after changing a watch's battery. Basically they have a vice that squeezes the watch until you can hear the case "pop" back together. Hours later, my wife pointed out the foolishness of doing this: assuming that it really did re-seal the watch against moisture, then the water that was already in there is trapped inside. My watch now has its own little self-contained weather system. I need to take it in and have them open the case, remove the water, and then re-seal it.
