I hope that is an online order with a store pick up.
I'm not buying one, but can't imagine having a $17,000 watch delivered to my house while I'm at work.
A person spending $17,000 on a watch like this isn't concerned with having things delivered to their home while they are at work...they'll either be working from home, have a concierge or someone trusted to sign for it at any given time anyways. One of the perks of being wealthy enough to afford such things is also being able to afford the luxury of having such security methods.
Hell, I'm not even close to wealthy enough to afford one of these top tier Apple watches, and I have a concierge in my building that signs for everything, logs it into a system that notifies me and keeps the stuff in a secured room with specific smartcard access for residents only.
