Hi Sqiffy  Have you any pictures   I think what you have got is an ATO clock that powers a coil that swings l/r on an arc, can you be more specific as regards damage. The ususall culprit for them not working was the transistor A (pnp) if I remember correctly. Ithink I have some info on them from the last one i did.

Hi Squiffy  Common problem with battery driven units , the battery leaks and the salts  corrode the terminals.  As Andy said the terminal can be replaced with a bit of careful soldering. I have even repaired some quartz units by making new terminals from brass sheet, but better still the link supplied by Andy for the bay contains plenty of terminals, mustbe some on there  Cheers.

Hi  Squiffy Interesting if you could supply photos of the control unit opened up.

I will do when I get to it. It’ll mean taking it off and dismantling it first and I’m working during the day at my new job. I’m now an apprentice saddler! At 54! Working in a proper old school type workshop

Leather working is a useful talent to develop. Don't forget to keep the leather scraps for making watch bands. :D
I may well be coming back for tips. My wife took up quilting about two years back, and as a result, I'm now pretty competent with a sewing machine (both stripping them down and servicing them and using them).

That is lovely I’m getting the hang of it but the industrial machines we use try to run away with me. 

I’m getting the hand stitching sorted and mainly doing repairs taking the load off the main guys in the workshop. My biggest problem is that I struggle to keep in mind the repair is just that. It does not need to be as good as new so I’m spending too much time trying to make it as perfect as I can. I’m learning though and loving it850B5A79-68BB-4147-A7F8-0124E9BBCD74.thumb.jpeg.ed0b9e07cd3341194b39275f4cef2edd.jpeg17316B05-3D47-4E1F-B9E9-FA9222B8C42F.thumb.jpeg.cf3edf26d29aeef4aa6fa3291fc5328e.jpeg

I managed to get the clock running by making a brass contact plate however although the clock runs and keeps good time the pendulum doesn’t swing as it should but more twitches so something is not right. 

The saddlery work is going well and I’m getting faster. Started training on the computer engraving machine so another string to the bow.

      Been there. Worn that Tshirt.  'ping'. Hands and knees. Nothing. Nada. 20 minutes? Ha! I found it 7 month later. How? Well, after advice from a member, I invested in a £4 UV light torch.  Hands and knees looking for a 'ping' from a Sekonda, found them both within 30 seconds. UV makes the jewel shine. easy peasy. Could have taken longer. Just lucky on the location of the search. Hope this helps.

      Thanks Dell. I thought about silver soldering. Have never done it but would like to give it a go. Do you think to put flux on the butted joint then run the solder in or to maybe brace it with a piece of scrap spring steel?

      Never and others. Yes, like you I do spend a fair amount of time reading the contents of this forum. I find it better that any other. Clear, lucid, no Prima Donas, and most of all an easy access without adverts. All thanks to Mark. God bless you mate. You give so much to many of us. What if? No Mark? Hypothetically. A forum. I did run a forum for a few years. Really enjoyed it, but became so engrossed that it did affect my health. I gave to to others to run. Not been back. It was very successful and rivalled a number of large paying sites. No adverts, no others but me. I did ask and listen to members comments and it worked well.    Costs Having a domain name, £10 annually.  Register the site with a forum company, free. Build the site using the forum company guide lines, free. It looked and ran almost the same a Mark's. All the same facilities. The cost was only £5 per month, but counted visits (views). If I recall, it was that price for 5,000 views. Each extra 5,000 views increased the price by £2 per month. Success was my own personal undoing. From £5 per month initially, it rose to £60 a month and looked like increasing. This was 10 years ago. I could not afford that, and asked it anyone would like to take over and someone did. I would assume that this is the price that Mark is funding for us all. His return is our continued comments on the internet about his course, and the fact that many of the big names on YouTube mention him as their Tutor. Those of us who have done, and are still using, his course, benefit. In comparison to other courses, I can't believe how cheap it is, and the value is exceptional. It is the structure that gives the value. Long may Mark reign. Ross

      Hi all, total newbie to watchmaking and I've had a bit of a mishap. Just completing level 2 and was doing ok, but I was just on the last part of the reassembly of my ST3620 when the balance end stone shot across the room, just as I was trying to see if I had put the correct amount of oil between it and the balance end, aarrrgh! Been on my hands and knees combing the carpet for 20mins looking for it but to no avail. Does anybody know where I can get a replacement from and what to look for please?? Thanks.
