Omega Cal 620 hairspring bent

Hey everyone

I was regulating my Cal 620 and looks like I've tangled my hairspring. Does anyone know the best way I can fix this myself?

Thank you, trying to learn how to repair balance springs and have messed up a few previous ones. For this, what exactly would I need to do to fix it?

This is probably not a feasible option for you, But as a general message to anyone interested, I took a week long class on hairsprings last year at AWCI. If you took this class, this would be a really easy 10 minute repair. It is really not as scary or anxiety provoking once you know what you are doing. Like mentioned above, get some larger springs to learn the fundamentals on before going to the smaller stuff. Two pairs of 5a tweezers help tremendously at keeping the plane flat during tweaks. We learned on clock springs first, making z bends, building the regulating curve, then making Breguet overcoils (just another z bend in the axial axis). Progress moved to 6497 springs, then 2824 springs, then to small little blued lady caliber springs. Cool stuff.

The meat and potatoes of corrections are: If you have a error in the round (radial), make a correction 90deg from that error. if you have an error in the flat (axial), make a correction 180deg from that error. Understand that the spring is in an archemedal sprial that grows in diamter with the length, but the regulating curve is a fixed radius to the center point. The regulating curve should be cetered in the regulating pins throughout the entire arc of the regulation arm.

They only offer this class once a year but I dont see it on the 2026 calendar. I would email them and let them know you are interested, they may open it up to enrollment. There were only two people in my class and its mostly just seat time to learn this skill. https://www.awci.com/event/watch-431-hairsprings-2-2/#
