DG2813 autorotor spins until all reserve is gone

[Ephry73]

I wanted to know if someone can shed some light into this issue. I had a 5517 project that suddenly spun out of reserve while it was sitting in the box. I actually know this because I had just taken it off after a "walking normally charge". The rotor spun off as if it was a dynamo and the then watch stopped. It holds a manual charge and you can move the rotor to "power it up" but after about three to four minutes it will spin off again. This bugs me because this one watch was working beautifully and kept great time(only gaining two minutes a week on average)

Any clues? I know DG movements are cheap, but if I can fix this one, I will be a better man.

Thanks in advance

sounds like the 'click' came detached or partially detached.

Is that on the rotor carriage?

I was just looking at an old DG movement with the rotor off and I can see that it would be a major dis-assembly to get to where you can see the problem. It's beyond my scope of work. I can definitely see that.

Hmmm, sucks. The movement other than that has been a work horse. Only had it for a year in October. Is there a spot on the movement I should be looking at?

I know this is a mechanical watch, but the click will stop the large wheel from rotating backwards which would cause the mainspring to unwind.

Gotcha. Thanks for pointing out. I think I know what to look for now. Makes perfect sense.

In this picture the click is the little shiny nub directly at 6 o'clock in the gap between the balance [censored] and the auto winding bridge. Just to the right of the balance [censored] screw.

These DG are actually a real bugger to work on. Much worse then the ETA 28xx series. They use an all in wonder bridge that encapsulates the auto winding parts and the gear train. It is a real PITA to line them all up.

Good luck

My post was censored. I guess I can't use the word caulk.

Gotcha. Funny that the word for rooster is sensored.

I swear that these DG's die after a year dead on. Must have a self destruct lol

Good thing that are only $20

---Update---

I was able to take the auto bridge off and tighten the stop "rooster" and the movement has been working fine since.
