How to wind a left handed mainspring using right handed mainspring winder

I don’t take responsibility for any broken mainspring. Please view and follow the steps carefully, you will success after destroying one or two mainsprings.

I have some Seiko 7009 and Citizen 8200 mainsprings to try on. Thank you for sharing.

Good luck!

It is tricky, but it worked! I could wind 8200 mainspring into the barrel with my right handed winder, saved me a fortune! Thanks again!

[@TimeOnWrist]

Congratulation!

Just wind it normally clockwise in smaller winder, then transfer to correct sized winder instead of watch barrel, then into the watch barrel. It's not rocket science!

[@TimeOnWrist]

Yes, that works too. But my method here works classically, a correct sized winder together with a correct sized barrel, and no rocket science needed.

I'm not sure I understand. Did you just use the right-hand winder from the opposite side of the mainspring? Doesn't the hook slip out of the mainspring since it's only designed to turn in one direction?

[@TimeOnWrist]

I inserted the mainspring onto the crank normally, not opposite site of it. The important point is that the mainspring catches the crank tightly enough, it can be out of the hook, but must fit snugly in the crank. Then I rotated the body of the winder, not the crank, so the mainspring could not slip out.

I'm not sure I fully understand what you are doing. You wind it on and then you do something with the small handle... what is actually happening when you are doing that and after you have the spring all the way inside the winder? I wish there was a narration as to what was going on.

I will try filming another video with better quality and explanation in near future. Thanks for watching!

[@perrybucsdad]

@@TimeOnWrist For the time being, can you explain in a reply what is happening when you are turning the small handle after the spring is completely inside the winder? Thank

[@TimeOnWrist]

The spring should release itself inside the winder, I just hold it firmly to make sure the strong release force does not cause any harm to the mainspring. Then I detached the small handle from the winder.

I think its not a good Idea to touch the Mainspring with bare fingers, leds to corrosion on the MS in the End ;) (Same goes for all Movement Parts ) But i like the Idea :D

[@TimeOnWrist]

Thanks, it is for demonstration only. You would find no trace of fingers print or dust in every movement which I have worked on ;-)
