@Navinu Amazon has a VERY robust distribution network where as Samsung likely has only a couple of hubs in US. I like ordering pre-orders and new phones direct from the manufacturer in most cases because I inevitably get better support if I need it or want to return.
Hope you like the watch!
Ordered Watch 3 from Samsung directly on 8/8/20 with a shipping date of 8/21/20. When I initially thought of pre-ordering, the ship date was 8/12/20.
Watch was delivered on 8/13/20 from Tennessee.
