This is so inspiring! Repairing damaged hairsprings, for me, is the most challenging task in watch repair. When I can do it correctly, it’s a wonderful experience. When it goes poorly, it’s disheartening. Watching this video is inspiring!
Brilliant! You can find the templates, but you can't just download the skill & intuition to know how to do this kind of thing. Thanks for showing this.
Just like Paul Schumacker said, it’s inspiring but also satisfying! I’m new as apprentice and already had my share of ruined hairsprings! I was wondering, where did you get those drawings? The one you cut off the schematic to adjust this spring. Thank you!
I got it at school , when learn about making a Breguet hairspring . maybe I can not sent all page of booklet. now I serch it, it's on www.tempered-online.com/curtis/PhillipsTerminalCurves.pdf Good luck !
Thank you for informative stream :) Can I ask where you buy the hairspring. I am looking for generic hairsprings that I can shape myself. Also longer one that I can cut myself?
Thanks for watching 😊 I bought it secondhand tool shop in SWISS. And I have many junk movements, then when I need to repair that using old new hairspring and taking off from junk movements. Sorry I can’t help you 😞

Thanks for watching ☺️ This book has same shapes and several size. I choose fit to diameter’s page. I think when published it , everyone can not use enlarge / reduce copy machines.
Very nice. I ahve unsderstood how to amke measures and calculate 62.5, OK, but what is the determinant data to get Nº 18 and not another number?? Thanks to share.
Thanks for watching 😊 This book has many same pictures. There are different size. I think Old days. They can not rescaling photocopy . No18 has not meaning just numbers.
I see the special tool to bend up the terminal coil. What is the name of that tool? I remember seeing a vid where regular tweezers were used to push the spring into wood and leave the bend in it. I have yet to do one but have a Elinvar spring to form and collet. I think using the tool may be the way to go.
Thanks for watching. ☺️ I use Dumont No.9. It’s bent up a hair spring. But there can use pocket watch size. Then I usually use fat tweezers and wood you said.
Did you have to resize the terminal curves to the size of your hairspring? If so how did you do that? I have the terminal curves book but when I print they are much larger than my actual hairspring.
Hola, soy Francisco, su canal me ha sido muy útil para mi aprendizaje. Desearía que me indicara dónde o cómo conseguir las pinzas y las herramientas para restaurar o formar el espiral Breguet para volantes. Le estaría muy agradecido. Espero respuesta. Un saludo.
Hola, soy Shigekazu. Thanks for watching. I bought those tweezers at Swiss secondhand tool shop. Maybe you can buy eBay. You have to buy Size 0 or 00. I can see size 3 or 4 in eBay but there are too big.
Hello, I have a Breguet spiral on a Rolex 1570 movement, which still works, but the spiral does not seem to me to be at 100%. The watch loses more than one/2 minutes per day. Do you believe that it is possible to repair the spiral or find a complete balance(I didnt find)?
Thanks for watching. Yes , you can fix it. Control to under 10 seconds 6 positions. But that need lot of time. If you get new complete balance , it have to control it. Of course I don’t have stock of balance.
In this video, using a hairspring for ETA6497. Not mach that movement just take process. Can get internet auction or parts shops. In fact, have to change a hairspring, I usually find nearly hairsprings from my dead stock balances, and adjust length and shapes.

Phillips was a mathematician and mining engineer not a watchmaker. The patterns shown in his book only show how to make a spring expand and contract concentrically, not how to make the balance vibrations isochronous.
@@tanakayawatch If you look at the balance spring of an old English precision chronometer, you will see that they never needed to bend the spring in any strange shapes to achieve isochronism. They have just a simple curved overcoil, either one two or three turns.
@@RollaArtis Exactly, I also agree. And now , regular use watches don't need those theories. But I'm watchmaker that I have to repair and need skills fits them.
Excellent work! But please please please change your background music. It's so annoying that I should turn it off to be able to watch the video to the end.
