Need help IWC Cal. 52 Mainspring

[Chamuko]

Hello,

 

New to the forum

 

I need some help I have an old IWC Cal. 52 that I really like, like 6 months ago the mainspring broke. 

 

So my old IWC Cal 52 watch needs a new mainspring and I haven't been able to find one.

 

Can you help me find someone who can sell me a new one or a similar one that might work?

 

I think that if I can get a similar one that my watch maker can set in the movement.

 

Any feedback will be highly appreciated !!

 

Thanks for your time.

You can find the mainspring size if you search for the movement on Ranfft :

In the UK I use Cousins, and order the nearest mainspring size
