Soprod P024

Probable

A Swiss alternative to the ETA 2824 that became widely used by independent brands after ETA restricted supply outside its own group. Its interchangeability with the 2824 is the practically useful fact: the two occupy the same space and take the same dial and hands, so a watch designed around one can be built with the other.
