I'm trying to order a mainspring

What do you mean that the spring is too big for the arbor? Sometimes with springs you must reform the inner end of the spring to fit the arbor correctly, this is what you have and what size spring you need, it is a 052 Calibre, 5 1/4 x 8 1/2 lignes, mainspring size in Dennison 3 x13 x 9 1/2.

Thanks so much Erin, I'm embarrassed to say I tried twice with a couple of alloy springs and broke them both. I've reformed other springs before and they worked fine but both of these just snapped without much pressure. But thank you the movement identification !!!!!!!!!!!!!
