Omega cal. 320 compatibility

Hi everyone
Does anyone know if there is any compatibility between cal. 320 and Lemania 1270. In particular train wheels, cronogragraph wheels and crown pinion. Thank you

I would ask @Archer . He's one of the most competent watchmakers I've ever heard or seen of.

the Lemania 1270 family is a weird intermediate step between what we call a 321 and an 861. You can in some ways think of the 1270 as a cam switched movement built on the 321 core. Where the 861 has substantial differences from the 321, the 1270 is much closer.

Yes I would assume some parts cross over based on pictures of the movement but it would depend on the part as alot of the inner workings esp on the chrono end are different.
