Depends:
**If Apple specified Saturday deliveries, then trucks will roll with the items.
**If you were supposed to get a watch on Friday and for whatever reason you missed the driver and requested it be held at the customer counter for pickup, AND that customer counter is open on Saturday (all the hours vary - some hubs are open as little as two hours), you can get it on Saturday.
If you're scheduled for Monday, and it's showing on UPS as received, you won't get it early. It's going to sit in a secure truck and not even unloaded until Monday morning.
So, will I get mine tomorrow? Leaning toward no on that one. There's no shipping information, no tracking numbers, there's no reference check result on the UPS site when I track by my TN. My guess is my watch is sitting in a distribution center and won't be picked up and start moving until later Saturday to get to me in time for Monday.
