Citizen Eco Drive

[Rosco1]

My first repair project is a friends Citizen Eco Drive with an E111 movement not running. I removed the capacitor and reinstalled it and the watch started running however there is a second problem. When the stem is pulled out it comes all the way out without pressing the release button. The stem is also slightly bent.

What should I look for  regarding the stem problem?

Hi   I have attached some technical sheets for the ecodrive .  If the stem pulls out altogether from the movement it suggests that the retaining lever in the mech is faulty or broken, if the stem is bent it will require replacement. The only way to find out is by removing the mech from the case and removing the dial and hands so as to be able to inspect the keyless work

Thanks for the information watchweasol , my friend has given me permission to attack his watch (brave man) so I will report my progress.

I have an eco drive from 96..hasn't  missed a beat in 25 years. They are pretty  hard to complain  about,and worthy of your time to repair.

I have a Citizen Skyhawk eco drive of my own which ran for 15 years without a problem. I replaced the capacitor with a new one and it still does not run. I suspect a fault with the solar charging but this will be a future project.

Possibly...did you leave it out in the  full sun for  several  hours?

Yes. I gave it several days of good light but no joy. When I fitted the new capacitor it ran for about two hours then it stopped so I guess that was the residual charge in the capacitor.
