Does anyone here make click springs for watches that you can no longer buy the parts for?

Just wondering what material you use for the springs?

I'm assuming stainless steel spring wire would do, but does anyone know of a supplier that sells the spring wire fine enough?

Indeed, steel spring wire is the one that you need. I had a hard time finding it myself and I had to ask someone that knows someone to send me a little bit.

I can't remember the thickness though... Think it was 0,4mm...

I think it shouldn't be hard to find but usually you'll find it in coils of a kilogram or maybe even more which would cost quite a bit...

This link below might be useful. Plenty of stuff to find in China. Have to admit I needed this some time ago but didn't think of trying ebay.

I thought it would be finer than 0.4mm, will need to measure one in the next watch I strip down.

0.4mm is 27SWG, which you can pick up reasonably from model engineering supply shops such as Reeves 2000.

Anything finer than 0.4mm starts getting trickier though.

My other hobby is restoring toy and sometimes model live steam engines and I regularly need to make new springs for the safety valves, which I used phosphor bronze spring wire for.

 

Of course some click spring are made of flat wire, and I haven't found a source for that at all.

Sure do. Cousinsuk have an assortment of 100 pieces of click spring. There is usually something to modify . Have some old AS and FHF click springs that i use also. Music wire is the best i think if you want to do it yourself. But need to be thinner then 0,4 mm . Hardest is those that have flat springs like in some ETA movements. 

BTW they are called shepards hook springs on cousisnuk . https://www.cousinsuk.com/product/shepherds-hook-springs-wristwatch

My mistake. I was talking about this click spring wire.

The wire that you need will indeed be thinner than that. I'm assuming it's usually 0.2, maybe 0.3 in some cases. I play guitar but never thought of using worn guitar strings... Might give it a try one day... Good to know.

      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

      By RobS · Posted

      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.
