Searching for help on an ETA 2824

[verbal]

Having more than one watch means there is always a watch not used for some time, well, my Seamaster has been on my ignore list for quite some time and I do apologise for that.... got that off my chest allright.

Anyway, to the point, when a watch hasn't been worn for some time I usually manually wind it a couple of times and then use it for the day or two.

Never had problems with that, only for some dark reason the ETA 2824 in my Seamaster is no longer happy with that;

Every time I wind it manually I 'drive' the rotor, meaning the rotor spins like a maniac while winding... It still keeps good time though..

I have a dead 2824 lying around but that is winding OK without spinning the rotor..

Anyone have a good idea where to look.? keyless works, some gear assy ..?

thanks in advance

Sounds like an easy fix as I had something very similar (The Zigmeister helped me out as I recall). It is the automatic winding gears that are messed up making the rotor engage while you wind it. Actually, all you would have to do is switch this with your other non-working movement. After the rotor is off of both, remove the auto winding bridges (I'll see if I can find the link for this), there should be two black screws holding it in, but you have to be careful not to unscrew something else. It will come off as a single part. You should be able to just switch this part and put back the rotor and should be good.

Ah, excellent, that's the information I'm looking for chris5264 !! , thanks a lot and thanks Pug for the image, I've removed the bridge on my dead movement to find out how it worked but never guessed that could be messed up. I'll replace them and see what the outcome is.

Thanks guys!

**edit** Problem solved!

changing the gears did indeed solve the problem.! great help guys, thanks

If you have cleaning fluid and the correct oil once it is cleaned you may be able to clean it out oil it and re fit it, basicaly what has happend is the oil in the ratchet devise for the auto winder is gummed up, there are 4 tiny, mmmm what are they called, blockers that alow the ratchet to wind the main spring in one direction but nor the other and ther are two per gear, The gold ones @10 and 8 on the photo above, if they are not free to move then the winding force as you hand wind will spin the rotor. Be aware of taking this bit apart as the "blockers" are very small and get easily lost in carpet!!!!!!!!!!!!!!!!!!!!!!!!!
