Waltham grade 225 watch restoration part 3: dissolving a screw using alum powder

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.

I've used this method to disolve a broken stem in a stainless crown. It was an odd crown that I couldn't replace. It took about a week, but the stem was completely gone. It did leave a black residue on the stainless, but it polished off and looked like new. Good luck with the rest of the job.

Thanks Peter - yes it looks like the residue it will come off. Hope that's the last repair. Somehow these things always seem to crop up unexpectedly as you go along.

Great tutorial. This is very valuable as these things happen often and a broken off screw is a nightmare!

Thanks! A true nightmare - I honestly have no idea how it happened! But you know, random mishaps happen all the time. I think it's important to be honest about that stuff.

Haha, right you are Boyd! I was surprised it worked so well, honestly! Definitely worth a try if you're in a jam.

I had the same problem with a Waltham 220. The star was completely rusted and the screw on teh bottom was also rusted. I successfully freed it up with wd40 and it all cleaned up nicely. Replaced the star, blued washer and screw.

Thank you for making this video. I would like to get into watch modifications and eventually gradually start Watch service and restorations. Do you have any directions as to what are some things I can be doing? So far I have bought basic tools more geared for modding from DIY watch club using a NH35 movement. (I successfully changed the date wheel, hands,and dial to aftermarket seiko parts not given by the company) I’ve read practicing on a pocket watch works well being that the parts are bigger and easier to work with. I also want to try and disassemble and reassemble the movement. Any advise on good books, schools or things that has best served you in the past to help build your skills. Thank you in advance! 😁

Hey Skyler! I took Mark Lovick's course on watchfix.com. It's really thorough and a great overview of the basic tools and lubricants you need to get into watch repair. Besides that, I've watched a lot of KZfaq (particularly the channels I link on my homepage). I also read as much as possible. Henry Fried's Watch Repairer's Manual is a great book that will take you pretty far. In terms of movements, I think starting with a Chinese ST-36 (the equivalent of the ETA 6497) is good, but you could also just take your NH-35 to pieces and I'm sure that would be a good place to start too. Watches from the former USSR are cheap (or at least they were before the war) and parts are typically available. I have done a lot of those. In general I think it's best to start with something that's working, so that when you put it together you'll know whether you have got it right. Good luck!
