I have the following delivery estimation, but sadly it's for a charger and not the watch, I am in the 2nd wave of watches 
The delivery dates are all really random, I have a watch with a 2 week window in May, I ordered a separate sport strap with a delivery of just 'May'.
I understand to a certain point not being able to say exactly the date on the watch if there is indeed a supply worry/delay, but the charger? I would of thought they would of just made them in bulk, with a much quicker turn around than the watches/straps.
Hopefully I will have a delivery from Apple on release day, but if I do, it won't be as fun as all of you that hopefully get the watch, I am not jealous at all
