I think where we disagree is what will happen with the medium market. I mean, if you own a steel Apple watch with a link or milanese band, that to my mind is nice enough to wear to all but the most formal events. So why would someone with a $800-$1200 Apple watch buy a traditional watch in that price range? I don't see that happening.
My thought was always that the AW would carve out the middle of the price ranges.
Low-end, say anything less than $200, would likely stick around. If you just need to know the time/date and didn't want to spend too much money, you could get a digital watch or Swatch for very little money. So AW doesn't play here.
High-end, anything greater than, say, $1,000-$1,500, would likely stick around (and perhaps shrink over time). Again, if you're spend this much money, you're likely not thinking about the price or just need to tell the time. Here, the appeals of luxury (brand, heritage, longevity, quality, personalization, status, etc etc) is what makes people buy these watches today.
The mid-end, well, that's ripe for disruption.
Check out the stats on Swiss Watch export by price point:

1CHF is roughly 1USD.
Look at 2014 numbers. Note that the bulk of units shipped were for watches that's 0-200CHF (18.4M units). The 200-500 CHF and 500-3,000 CHF segments shipped less units, and is likely where the AW plays (and more in the 200-500 CHF segment). Of course, you'll see that most of the rev is in the 3,000+ CHF segment.
So this type of stats on Swiss, German, and Japanese watches is something to keep a note of going forward.
