Hello,


I see that some people here have lots of knowledge on watches, and I need some help.


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


Any idea of where could I get one or a similar one that might work?


Maybe the size of it so 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.


Rodolfo
