Hairsprings are normally not something you can buy like you buy a balance staff or a pallet fork.......
You may came across someone who sells raw hairsprings but to find the correct one, to vibrate it to fit the balance, to mount the collet and stud and to shape the outer coil is not an easy task......

The hairspring is timed with the balance at the factory and usually sold as one unit. Now, to find a new Balance Complete for your watch might be difficult so my best recommendations are a) Try to find a donor movement with a functioning balance or b) try to rescue the mangled hairspring.

If the hairspring is not broken and does not have very sharp kinks, with a lot of work, you can often at least shape it back to a working piece.......

Hi,

more details are needed: what diameter is the movement (mm please)? Do you know the calibre or name of your movement? Is there any info on the dial?

That hairspring requires a bit of work but it does not appear to have any sharp bends that would break when straightened.

Depending on your skill level, time and patience you have to decide if you want to give it a try or go for a replacement....

Good luck any way you decide to go!
