Hello, and thank you for the add! Newbie here with watch building in general. It's my first time putting together a watch with 2824 clone, and am having issues with stem reinsertion. Before removing, I pulled out the stem to the time setting position (but I have seen on some strings that there are people who suggest the winding position). Did I put too much pressure on the release button? Maybe. I've tried all the advice I've seen on the issue: insert with the dial side up, gently jiggle the stem, I've broken down the movement a bit and reassembled the keyless works. I've watched all the vids I could find on how to do this, making sure I've put the yoke in the right grove in the castle (crown?) sprocket (sorry if I'm using the wrong terminology for these pieces). I'm pretty sure I've set the pieces of the works in the right places, hooking together where they should hook together. But the stem, when inserted, engages nothing. It won't engage anything. I can't wind the watch, set the time/date etc. It just falls out. I must have really buggered something up. Any suggestions where I might look?
