I hope some new timers will have some better i deas for you. some time back in the mid to later 90s I did a hole thing on this on TZ. when i had webTV. Iam sorry to tell you I had some health problems and then TZ had us all change and register like 3 times and I can not find where my stuff is or what my old name was on the site or my old email address. back then you did not need all this reg name and handle & passwords.
If I ever find it I will remember to sent it to you. It showed the hole process. even a live shot with my drive belt slipping and starting to smoke. a very cool shot. I have it on film somewhere.
But I am sure its going to be OK as it is. Make sure all of you after a long day take it off and with a damp cotton (wash cloth) wipe down the back around the case back and lugs to get all the salty acids off it. You would be amazed at the things that distroy S.Steel watch case that come out of our body.
