Thanks for the kind welcomes in the introductions forum! Also for the advice, but now I must post what the problems are but no diagnosis and the causes. I appreciated the information on what battery would replace the Watch Battery 343 which was on the last battery I had in the watch. It would have been a mercury battery and those are no longer sold. One kind soul suggested an AG 10 would work, and I went to Batteries Plus to pick one up. They assured me a 389 RENATA is the equivalent and it's listed as a Silver Oxide 1.5 watch battery. The dimensions were the same (diamter and thickness) as the 343. I was excited to see if it would produce movement. But it did not. I also moved the hand with the stem but no movement happened. I attached a photo of something I noticed about 25-30 years ago when I set the watch aside, which could be a clue. There is a 3-pronged electrode inside the case, that sits almost flush to the inside atop what looks like gold colored mylar. I suppose that's an insulator. But, the electrode can swing side-to-side. I moved it carefully to one side for the photo. The 3-pronged electrode on the battery cover is mounted in the center. It occurs to me that the electode inside the caseing could be the issue but I have no experience here. I also took a photo closeup of the BENRUS case. Two lines below the stamped name it is stamped "OPEN THRU CRYSTAL". Maybe fools rush in where angels fear to tread. I have seen watch crystal lifts, but don't own one. I know I would need that and some tools to begine this. It will of course have repairs beyond my newbie abilities. ShouldI gather a few tools and learn now? I'm not in a hurry and I certainly know a tool or tools is not part os the repair cost. But if buy the tools and treat this what like a medical cadaver to learn some things is that worthwhile? And maybe, just maybe, I can bring Frankenstein back to life. Mark

A few days ago I posted a question about the case for this ESA 9154 movement sold by Wittnauer. However, this post relates to the movement. I just can't get it running. The train seems free enough, the battery is good, and I have tried two different circuit boards in it, but still no go. At first I was wondering if some other knucklehead got their hands on it (pun?) before this one did, and demagnetized the balance. However, when I short the pins of the transistor (switch), the balance will oscillate a bit, albeit in very short arcs. It's like it's switching back and forth too quickly. That just a guess. If the train was binding, or the balance wasn't being magnetized, I'd think it wouldn't twitch back and forth like it does when it's powered. The watch doesn't appear to have had a battery meltdown or anything, but it just doesn't want to work for me. I have a Wittnauer with an earlier, ESA 9150, that is running like a champ now. I cleaned and oiled the movement. The balance swings for a bit shorter time period than the 20 second standard and the train moves fine as it does. Does anyone have any clues on what could be wrong? The troubleshooting section, for the coils specifically, is geared towards the ESA9150, which seems to have an extra test-point contact. Parts for the 9154 seem hard to come by. I have 3 other parts movements, but of course don't know why they became such. Any help is appreciated. Cheers.
