Here's one I prepared earlier..

 

After cleaning both the nut, and case back with acetone, I added superglue, and placed the nut on the case back with a weight for 24 hours.

Next day, left with this..

Then unscrewed as per video, you can hear the dirt/grit in the case back threads as I unscrew it, clearly needs cleaning.

 

 

 

One that is done, soak the case back and nut in acetone for another 24 hours. Not worried about dissolving the nut nylon lock washer.

i deliver to duke hospital and their research facilities. one of their "refrigerators" is cooled to -80 C....i'd look like a nut if i asked to put my watch case in there. lol

errr....which nut goes into the fridge? :D

 

Sorry ramrod, I couldn't resist! You are not alone, I would have liked you to see my family's faces when they first saw what I was doing with the watch when I first started doing this! :)

 

Cheers,

 

Bob

It is supposed to work on bezels but I have mixed feelings about this one...it is a cheapo from ebay...not too cheap though! I used it to hold the base and knock the nut off with the hammer. Remember I used epoxy which is more resistant to acetone than super glue. I would go with the superglue any time after this experience!

      I take it that you're comment re the Unicorn is 'tongue-in-cheek'? Would any of the watches that are on the link I posted be likely to be radium watches? What period was that prevalent in and when did the practice stop?

      As much as I hate Facebook, can a forum-like place be set up on there? Free and the ownership can be taken over by the next person whenever.

      Mechatronics Engineering v Mechanical Engineering

      By HectorLooi · Posted

      I existed before the term mechatronics engineer existed. I had to combine electricity, electronics, pneumatics, hydraulics and computing just to keep my own equipment working. I have never sub contracted any of my own repairs to the suppliers because I know I could do a better job. For a long time, dental suppliers in my country would bring their dead equipment to me that their own engineers cannot handle. I have accidentally embarrassed a couple of hospital heads of engineering by demonstrating their inadequacy.  I think mechatronics is the most under-appreciated, under valued of all the engineering sciences. I had a part-time dental assistant about 25 years ago, who was studying mechatronics in the polytechnic. She was absolutely clueless about the job prospects for a mechatronics engineer. I asked her about her aspirations and she replied that she really wanted to work in the games industry.  In our dental profession, equipment have evolved from simple mechanical to electro-mechanical to logic-driven electro-mechanical and currently to computer driven machines.  The medical equipment suppliers who employ mechanical engineers and/or mechanical engineers cannot cope with the repairs of the newer equipment. And many times end up changing whole modules and whole machines just because they cannot repair them. But I think HR is afraid to employ a mechatronics engineer just because they don't know what a mechatronics engineer does. Mechatronics is much more fun. It combines almost all of the engineering sciences and produces an all-rounded engineer. But until HR changes their mindset, not all door will be open.
