Its like this on the left.

I have never heard such tommy rot. I well dressed screw driver blade and the correct size for the screw and you need a steady hand is all that is needed. The more expansive screwdrivers have a easier rotation in the fingers then cheap ones.

Why?

I used to make parts for clocks such as pivots, mounting wheels that sort of thing. Add a little Loctite will do the trick. Make sure you buy the right type.

Not that easy. You need to know a bit about them, other wise you could waste you're money and end up with a real turkey.

It works extremely well with movements that have seawater in them. Being a watchmaker not far from the seaside I used to get any amount of rusty watch movements to repair.

Nothing wrong in that. I would have said the same thing. I expect you have rusty parts and that is why it won't release.

Your confidence grows with each success. You should advertise in watch magazines. With your skills, you could make a lot of money. There are very few that have the skill you have. Loads of watch repairers, very few watchmakers. Nice clear photos too.

If there is no friction fit stud. You have to fit the hairspring to the balance so the roller is in the center of the pallets. Most repairers will mark on the balance the position where the stud should be . This helps when fixing it all back in place.

Just replace it with a new one.

Will that ring come off? If so you might have height on the glass to remove it. If it doesn't come out from the back then it has to be the front, in which case it will also have a two piece stem.
