Question on new reverser wheels?

[Timelord]

Greetings fellow members,

 

I just received a  new eta 2836-2 mvt from ebay and never really had a problem from the seller with any previous mvts

 

I intended to build a sea dweller but upon completion, tried to wind it up to get it moving.  The rotor kept spinning like crazy.  I thought that reverser wheels are either dry or possibly dirty.  

 

Stripped the whole automatic assembly, cleaned it all, lubed them and replaced them back in the movement!

 

NO change!!  Actually they performed worse as rotor went like a propellor upon manual winding.  

 

Has anyone experienced  the same problem with new and just cleaned serviced reverser wheels doing this???  I just can't work out what could have gone wrong.  Maybe my skills or lack of knowledge!,  I am all ears/ eyes for any inut.  Thanks!!

It might help to hand wind it slowly with the case in a vertical position so the weight will fall to the bottom.  Maybe not depending on overall condition.

ETA 28xx auto wind assemblies/reversers can be a pain. 

If you hand wind them...everything wears out.

If they get dry/dirty...the rotor spins and the pivots wear out.

If you over oil the reverser ratchets and everything else...the rotor might still spin but the pivots will live long and prosper.

 

The 'rule' is to use super light oil on the reverser ratchets, heavy oil on the pivots, a bare minimum of hand winding, and move around a lot when wearing the watch.

Here is some info:.

I thoroughly clean mine in a 3 stage clean/rinse/dry & then treat with Lubetta 105.

 

Sometimes though, they are beyond saving and need replacing. They are fairly expensive little wheels.

Gentlemen!!

a world of thanks for your input and advice!  I know these little cogs are very pricey to replace, made worse when I have just spent money on a new movement.  I did not expect this!!

I have purchased second hand movements for a third of the price that still run flawlessly!!  I was beginning to think that the automatic device was faulty at manufacturing.  I jam glad that I am still with a chance that I don't need to replace them.  Keeping fingers crossed!  Thanks again!
