Don't knock it until you've tried it.
That said, I'm having a sapphire put on the Meister that I have on order. Very happy with the durability of my Max Bill acrylic. It has handled a fair few drops and scrapes well, the only thing to damage it so far was when our puppy got hold of it for a good chew.
All this fear of acrylics is bullshit. There is a reason they put plastic on instead of glass on their dress watches...it looks freaking awesome. Junghans do a very good scratch resistant coating too although that stops polywatch from working.
Can't comment on vintage as that's not my bag but if you're considering a handwinding Max Bill (great choice) I'd suggest also trying on a handwinding Junghans Meister for comparison. They're super slim, dressy and well within your price range.
On balance, I prefer the Meister ...just. The thin factor nudges it ahead.
