Accutron 214 astronaut

[Watchit06]

Ok. Working on a 214 tuning fork astronaut! I am getting dizzy trying to fix this one. I lack the experience on tuning fork watches. So my big question is what is affecting the gears from rotating on the dial side. After I install hands? The cannon piñion rotates well on its own, the minute wheel will rotate if added, then after I put the minute bridge on it will stop, but this isn’t happening with a different bridge(without hack) a lot shorter bridge just covers minute and setting wheels. So that’s how I have it on now, saw rotation of gears, got excited so I dialed up and installed hands, watch buzzes the second hands spins, but the hour and minute hands don’t move... so my quiestions are as follows. specific to astronaut model only
1. Does it matter if I use regular 214 minute bridge?

2. What causes the rotation of dial side to seize, when the stem hasn’t even been installed?

If the hack is missing ( watch can’t be hacked) correct? 
 

if stem is out of the casing, it can’t be the stem! Right? 
 

I am sure I am overthinking. Your help is appreciated. 
TIA

Ps. I did replace the centre second pinion jewel with new shatton.
