In my opinion it's absolutely fake. I have seen those without the Heuer shield before. I could have picked one up at my local flea market for as low as $10 a few months ago.
It's very easy to tell the Heuer shield was printed at a later, much later date.

This is how it looked originally

It's rather funny how most eBay sellers want you to believe every Baylor they are trying to sell is Heuer Made, calling it a "Poor Man's Heuer". Annoying as well.
