Help needed - Flea market find

Any info or idea of this is legit? I can't find any date only models that match. For $10 I figured it was worth a chance. Crystal is pretty scratched, but the automatic movement runs and keeps time

IWCs are often faked. The caseback says "Speedmaster" so hopes are not high, sadly.

It's not

Hit it, vigorously, with a hammer.

The dial is horrible.

The case back is comically bad.

It's a fake that isn't even worth 10 bucks.

I figured, but took a chance. Worth a $10 lesson to look closer

It's a fake on a $3 silicone strap.

You have a better chance buying a lottery ticket than finding an authentic watch of a brand like IWC for $10 at a flea market.
