Stubborn Screw-In Back How To....maybe


Recommended Posts

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.

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,

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!
