I found this movement stashed with some junk jewelry. No case or hands. Since I could see the hair spring was broken, I thought this is the one that would be a great movement to start with to learn how to remove screws, etc. since breaking it more seemed unlikely. I have no expectation to get it running. I simply want to take it apart and put it back together. However, I can’t figure out how to let down the mainspring. It appears to have no power by the lack of impulse to the escape wheel, still it would be nice to know just in case any residual power is simply not making its way to the EW. The tool is what I use since the movement has no stem or crown. I hope someone can point out where the click would be, or if it uses some other system, what that would be. Thanks.
