Hey there!
The top one, IMO, has had a massive polish to the point of the case looking very soft.
The bottom one, in comparison, seems to have been spared and appears to be a step case in stainless steel. Suspect is the crown, which is slightly off angle (suggesting a mangled stem/setting lever). The dial appears legit, though more experienced Longines collectors can add more.
Would you have more pictures of the 2nd one for analysis?
