Hi all,

As a proud level 3 assessment owner I started to buy old watch movement for repair. I did have few success restoring old ETA 1258 (Enicar watches) and going forward bought an old omega seamaster equipped with a 1012 movement.

I found quite easily the problem with the watch : the balance wheel missed its jewel. I didn’t feel like putting it back with the shellac (too complicated for my level :) so I bought an old complete balance to replace the faulty one. So far so good I’ve put back everything after cleaning the movement and oiling all the different part (I only use D5, 9010, 9415 and grease).

The problem I have is whenever I put back the balance the movement doesn’t want to start. Without the balance if I wind the mainspring it turns freely and I can see the escape wheel turning, when I put back the palet fork it oscillate between entry and exit position when I push it with the peg wood. But the balance doesn’t seem to work.

Could you help me to find what’s going on? or at least give me a path where to start? I couldn’t find any help in your course for that particular case…

I can send you pictures or video if you want just tell me what you want to see.

My next one will be a Seiko 7017A with the flyback chronometer, can’t wait for you to release the level 4 hopefully I’ll find all info to restore this one as well :)

Thanks by advance and a happy new year

Maybe your endhsake is insufficient. Loosen the balance cock a bit and lift the cock. Sometimes when swapping parts over the clearances could be different and lifting the cock a bit could make it run.. Its not a cure as the issue will still need to be resolved but at least you know where the problem lies.

      Part swapper to part maker

      By Neverenoughwatches · Posted

      Thanks Rich, its really not that difficult to make them, simple ones anyway. Cousins didn't have the part though i could find it on ebay at 6.50. I figure i earned about £1.50/ hr . It paid for the diamond files i bought.

      How to remove shock settings from Smiths 512 movement

      By mikepilk · Posted

      If you look at this thread, you can see I had exactly the same problems with balance springs with 2 prongs on a Smiths 627. The slots in the chaton were not big enough to get the ends of the spring out. I had to bend them to get them out and back in. Not ideal. I don't fancy having to do it again as they could easily break, and where would you find replacements? I didn't come across the 3 prong type.

      Breguet Exhibition at London Science Museum

      By mikepilk · Posted

      I visited the Breguet Exhibition today. https://www.sciencemuseum.org.uk/about-us/press-office/rare-timepieces-unveiled-new-display-science-museum The Science Museum now holds the collection of "The Worshipful Company of Clockmakers" - "The collection includes more than 600 watches, 90 clocks, 30 marine chronometers and a number of fine sundials and examples of hand engraving, mapping the history of innovation in watch and clock making in London from 1600 to the present day." It's well worth a visit. They have some amazing pieces by the likes of Harrison, Breguet, Tompion etc . I've visited twice before but decided to go and see the Breguet Exhibition. Maybe I was expecting too much, as on reflection, "More than 20 extraordinary timepieces designed by inventor and watchmaker Abraham-Louis Breguet " isn't going to take up that much space. In reality, it's just one cabinet. But, Oh those watches, stunning 🤩 , e.g. (No 1297 was made for George III and is valued about £1m)   I tried a couple of pics, but with subdued lighting and taking through glass, they aren't good. I like thin hands on a watch - how about these (I think this is a split second chrono)   And this one, with all it's complications, is only 10mm thick !   What I found very interesting were a few very old machines for making watch parts, like this 17th Century gear cutter. The disc below has concentric rings with holes in, so that is can be set to cut varying teeth numbers.

      How to remove shock settings from Smiths 512 movement

      Firstly sorry for poor image quality I only have an iPhone for photos.    Im working on a 512 movement and I’ve had some trouble with the “jewels”. I’ve got the metal one out, but when I tried to put it back the three sides of the spring seem to need pressing all at once to fit it as there are three “holes”. I get two corners in but as I go for the third the first two pop out! Constantly I’ve lost the spring. I’ve done the similar ones on seiko movements without trouble. Assuming I find it/a replacement, what am I missing!   on the other side with the only ruby in the movement is a setting with no “gap”at all. How do I get the spring out, and of course get it back in!    What am I missing!    thanks in advance.    Rob

      Links like that are the reason I routinely donate to the Internet Archive - they are the last safe house for a tremendous amount of useful info that is otherwise lost.
