Automatic watch not working after reassembly(Vintage Seiko 7002 Divers Watch)

[RyanGreerMcGilloway]

Hello there,

 

The other day i took apart my Vintage Seiko 7002 Divers Watch to ascertain the issue with the second hand randomly stopping. i believe i resolved the issue because the mainspring barrel cap had popped off and needed clicked back together, i had replaced the balance (i had accidentally bent the hairspring), and the 2nd reduction wheel reverse threaded screw(because someone previously had sheared the thread. 

Now, last night after i received the components in the post, i had reassembled the watch and now the balance wheel is not turning and when i slightly put pressure and wind the mainspring, you can just hear the spring releasing its self and also, when i turn the crown to fiddle with the time adjustment, the hands will turn rapidly with no control.

That can easily be the escape wheel which has broken one or both pivots, and is not resting anymore against the pallets.

I must admit ive just been researching that and i dont believe they're broken but maybe just not sitting in the bridge over plate. 

It must be why when i turn the mainspring, the two time wheels turn but the escape wheel does not.

How can i put this in place correctly, because it is very fiddly. 

 

Thankyou very much!

First check well if the pivots are still there and straight. And then you need patience, and developing dexterity. I think some good advice has been given in the other thread you had opened.

Will this also stop the hands from winding uncontrollably?

Yes, if the escape pivot is broken, the seconds hand will go pratt and whitney.

There is also a chance the pallet jewels are disalleigned and let escape teeth to escape.

Helloe there,

 

After deep analysis yesterday afternoon, i believe the escape wheel top pivot has sheared off as when the top plate was and i had tried to move the wheel with and needle and magnifying glass, i see there is a heck of a lot of play even when the top pivot is central to the appropriate jewel. 

 

Am i right in thinking that this has broken?

That is what Nucejoe and I have told above already.
