I cannot advise or recommend any such action.
In the current state, it was me with the apple shirt on I would direct the replacement decision to a lead or manager.
apple care covers 2 damage replacements (with a fee), OP is not looking for a free warranty repair.

To the OP
It says "accidental damage" and mentions nothing about the screen,
a dent would be damage.
Your best bet (and probably lowest time involvement from you) is to call phone support, that's what I did when mine hit a tile floor.
when you go into the store, they'll look at it, say "yep, it's broken", You'll probably have to handle the replacement through shipping anyway (at least that was the case for me, I walked into the store and asked the greeter, and that's what I was told)
On the phone, they'll give you 2 options.
option 1 (time 2-3 business days to your replacement watch)
If you've got a credit card with room on it, They will place a hold for the full cost of a replacement watch, and ship you both a replacement watch, and a box to return your watch in (or maybe just a new label for the box your replacement came in), once they receive your old broken watch, they'll release the hold.
I did this, and had my new one in a couple days. You need to get your broken one in the mail within a few days as there is a time limit on the return. (they'll explain it all on the phone)
option 2 (time 5-10 business days to your replacement watch)
they'll ship you a box
you put your broken watch in that box
once they receive the broken one, they'll ship the replacement.
both options only ship the watch itself, no bands, no charger or any other accessories.
