Seagull ST3600 Balance Wheel Hairspring

[Strummerus]

Hello everyone. I have a Chinese 6497 movement (Seagull ST36) with a broken hairspring. I can’t seem to find a replacement anywhere online. There are plenty of replacements for 2800 series (Seagull ST21). There also 46940 balance wheels available which look similar. 
 

My questions are pretty dumb. Can I use either of these in my ST36? Also, does anyone know if ST36 balance wheels are available anywhere? Sorry to trouble everyone but I’m new here.

I don't know anything about parts compatibility or availability, but would it not be less risky and only a litlle more expensive to replace the whole movement?

Yes, you are quite correct. I just thought it might be interesting to give this movement a new life, haha.

information and parts are in short supply regarding chinese watches, therefore as Klassiker said replacement is the least painful way

Is this a watch or just the movement? 

As said Chinese movements are cheap, however, what to do if the movement isn't cheap or parts to it are no longer available?
