You need a winder that first is the right direction - some wind the spring in in one direction, and others wind in the opposite direction.
You need the arbor of the winder to reasonably fit the inner coil of the mainspring - can't be too large or too small compared to that inner coil.
You need the barrel of the winder to closely fit the inside diameter of the mainspring barrel drum - can;t be too large at all, but has to be large enough to fit pretty much all the spring into it to wind it all up.
What parameter isn't fitting the spring or barrel?
