It looks like the marking is engraved instead of stamped. Could be enhanced after stamping. Fonts look ok. Is there a risk that the movement is a fake? Sorry if the thread is not the correct one

 

Hi,

Look at this page.

Your watch / movement looks ok. Perhaps overcleaning with polish / engrave tools

 

Thanks!
