Seiko 6309 can’t wind

[Nucejoe]

 Did you visually check the holes barrel arbour fits in? 

 Barrel can rub on mainplate or barrel bridge in case it sits tilted OR barrel lid isn't fitted level/flush level with barrel wall, but  three barrels weren't all bad.

 

 couple of test ;

Loosen screws to barrel bridge up to two full turns, see what happens, as barrel or the fixed end of the click spring itself can rub on barrel.

Remove the ratchet wheel and try turning the barrel with a wooden stick,  barrel and gears in the train should spin then.

Disassembly is not just tearing down the movement , unscrew ing every screw you see,  ITS A PROCESS , in which you have a chance to test/check functions of each piece, shakes, unimpeded function of each piece when fitted in place,  if you just clean and put together all part, any  issue that was there has gone unexamined.

In case  above tests revealed nothing, you might end up  tearing down the movement again.

In pictures couple of ratchet teeth seem worn/bent, which may rub on the bridge.

Without reading through..have you verified that the arbor is hooked to mainspring ? This is one of the unseen connections the ratchet wheel has with the barrel. The other would be the mainspring's bridle to the wall of the barrel.  Is that intact/ badly worn ? Is it overly slipping ?

Forget turning the screw, take it out , hold the ratchet wheel in place with a stick and push the ratchet wheel...can you see the square of the arbor turning ?

Just a stupid question: How did You release the power of mainspring when disassembled the movement(s) for the first time? My guess will be that You just turn the screw a little as to be able to lift the click and then let it go suddenly? If so, then You will have to open the barrels and see what has happened inside. There may be some chance at least one of the springs to be not broken and still to be possible to be hooked to the arbor.

The thought that the arbor doesn't turn and the reason may be the arbor itself or the ratchet wheel is so naive that it is actually very hard to be commented. By the way, the down side arbor pivot is seen on the other side of the movement and it is not a problem to see if it turns or not. If the spring is hooked to the arbor, then it will start winding and You will feel resistance, the ratchet wheel will turn a little back by the spring torque until the click has engaged. If the train of wheels for some reason doesn't turn, then some energy will be stored in the mainspring and You will know it when removing the ratchet wheel off the arbor. Of course, I will guess that this is not the case, and the spring is just not hooked to the arbor.

Releasing the power of the mainspring can be a challenge for these Seiko watches where there's no connection between the ratchet wheel and the crown. It's so easy for the screwdriver to slip out of the screw and when that happens with the click held open ... I'd love some tips on how to do that safely, but that's a bit off topic here, I think.

Let most of the power rundown before you try using a screwdriver and releasing the click.

You can release the power in small increments if you don't feel comfortable letting the screwdriver slip between fingers in one go.

Thanks for the advice. Yes as a novice, it’s difficult to dismantle a movement without any experience and is a learning process. I understand with time, to slow down and access is the best way forward. Practice is what I need so thanks for the tips.
