Here I dissolve a broken stud screw on the Waltham using a teaspoon of alum powder in water. I had screwed the stud in and out several times with no problems, but after coming back from a weekend away, I found the screw broken! Go figure. I had heard about this technique for a long time, but never had reason to use it until now. After a few days, I can enthusiastically endorse it.
