Well if you want to try it log-in to UPS My Choice and find the page with the Calendar. Then click the My Settings tab and then click "Manage Delivery Addresses".
My building is a 12 story high rise in Orlando with two separate banks, two law firms and a real estate developer in it. I'm pretty sure we're registered as a commercial address.
Tried it. UPS hates me.
Watch from the Tennessee distribution center. Typically, Apple has several distribution centers for product launches, including Newark, NJ for the Northeast. I'm in Philadelphia, and I surmise this is why I haven't yet found my shipment info on UPS despite my watch having updated to "preparing for shipment" yesterday around 5pm.
