Not a straight lug but it's made of the same stuff.
Yep! It's possible to survive... as long as it isn't over polished. To my knowledge this watch has been cleaned but never polished.
My old man was a truck driver through the 70's and 80's and later in the 90's a warehouse manager. He wore this to work everyday for 35 years. I know it aint a straight lug Speedmaster but the twisted lug edges of the later 105.012 models are just as vulnerable to wear and you could shave with these edges.

The only part of this watch that is showing a fair bit of wear is the part that was in constant contact with the wrist for 35 years: The case back.

So it would seem that it is possible for a case to be relatively free from excessive wear after 50 years. Even if it's worn to work every day. Depends what happens to it during it's life.
