The setting level does look off on the spring but I think all you can do is to refit it and see how it goes as a replacement will cost the same as it cost for the watch. Edit Just had a look at your original photo and trying to work out if the balance cock is original or if it's has been butchered?

if you pull the stem out it goes into a mode where you can rotate the hands and put them in a specific place like on top of each other it makes it a lot easier when removing the hands. then yes it's always nice to put the stamina crown or the stem back in the watch whenever you're handling it as it gives you something to hold onto or for letting the power off or setting the hands it's just nice to have something to hold.

The case opener in your first picture is for Rolex style casebacks. The case holding vice in the second picture is cr*p. The moment you start turning the caseback, the entire vice would turn together with it. The crystal/caseback press in picture three would probably work. But you have to make sure that the screws of the upper and lower tool holders are properly aligned. Some of them don't line up properly. If you're using a traditional caseback knife or a Swiss Army knife, you're chances of slipping and scratching the caseback is very high. No paper or plastic sheet will be able to protect the surface if you slip. The secret is not to slip. 🙄 A Seiko style caseback knife is less likely to slip. It is used with a stabbing action to wedge the blade under the caseback. Don't try to pry/lever the caseback off like a tin can, that would only lead to slippage. The wedging action would pop the caseback off in most cases. Only in really stubborn cases where the blade has wedged in but the caseback still hasn't popped off, then some twisting and levering is permitted to lift caseback to pop it off. Very rarely, you'll come across some really tough casebacks that would require specialized tools to open the watch. But we'll leave that alone for now. -

After the video I managed to unstick the crown wheel ring. I used a scalpel then a screwdriver to lever it off its post. It was so stuck at one point I thought it wasn’t supposed to come separated. Since I also washed the parts and dried them. I am about to start the reassembly I have to say I am a bit worried about the balance spring
