This literally a tiny issue, but It would be interesting to know how to deal with these kinds of things.

 

As you can see from the picture below, there seems to be a bit of damage to the plating of this 1969 Speedmaster cal 861. It’s very small, but how do I make sure the damage doesn’t spread? I guess I should remove all loose plating, but should the surface be treated with something too?

 

There was some greenish goo over the area when I first opened the watch, could it be a reaction or another watchmaker that put something on it?

The green goo is usually the oxidation of copper.  Most copper compounds are green or blue green.  Anything you can do to prevent the surface from contacting the atmosphere should stop it.  I don't know what works for watches but for other things sometimes people use varnish or wax.

That is probably corrosion due to a bad gasket or something done by a previous watchmaker. I don't think it will spread. But you should need to look over your gaskets. The little i can see i can see that it's in bad shape. Maybe have a service done or at least a check. 

Omega has coating called rhodium.

Thank you for the replies.
i wish I had taken a “before” picture, but I guess you are right about the stuff being oxidation. A surprisingly large amount perhaps, but it would match the description.

Yes, the gaskets need to be replaced for sure. But do you think there is something that could be put on the copper to prevent further oxidation? I mean, it should be something that stays put.. :)

Have seen some rhodium repair on cousinsuk. Have it in my watchlist but never had come to test it. It's called magic rhodium. Someone here maybe has tested it? https://www.cousinsuk.com/product/magic-rhodium?code=R49276

      Stem removal after fitting hands

      By PeterS · Posted

      Yes, the seconds hand is the longest and goes almost to the edge of the dial. I can’t quite picture it how you do it on the rubber pad

      A don't think so it leaked or damaged it because the watch itself works it just the buttons ain't working not connecting with the circuit board have taken more pictures of where the buttons makes contact with the circuit board.

      Stem removal after fitting hands

      I think what peter means oh is once he has fitted the hands and  checked for  alignment if them and that they dont foul, how does he then hold the movement to remove the stem in order to case up. The dial cannot be laid on a cushion or in a movement holder as the hands will get damaged. This can be quite tricky for a beginner, what i do is  to stand the movement on edge on a rubber pad so it doesn't slip. Hold the top edge with one finger then my dominant hand uses 3 fingers to press the stem release and flick out the stem. See below peter, leave off the second hand as this is the longest and gets caught the most, then fit it once the stem is out. Alternatively place the movement in one of the cup style holders, i imagine this is what they are designed for. They only touch the very edge of the dial.

      Yes I understand that. What I’m asking is, after the hands have been fitted, it’s been checked that the hands do not touch etc. then I need to remove the stem to fit the movement in the case. I have the push type, I need to turn it upside down and push the setting lever post and pull the stem out. But of course the dial and hands are in place and I have a glossy dial with lume dots and I do not want to cause any damage while it’s upside down pushing on the post of the setting lever.

      You have answered your own question. You just push the setting lever nipple in or if its the screw in type unscrew it a little. You should always remove any hands and the dial before putting it in your movement holder.
