Just hours after Apple Watch Series 2 pre-orders became available, shipping estimates for most 38mm and 42mm models have slipped to 2-3 weeks in the U.S. for new orders placed through Apple's online store.

Apple Watch Nike+ models are expected to ship in late October, while the new 42mm ceramic Apple Watch Edition ships in 5-7 weeks. Apple Watch Series 1 models remain available for September 16 launch day delivery.

Best Buy, however, still appears to be offering shipped-to-home September 16 launch day delivery in the U.S. for several Apple Watch Series 2 models, including aluminum and stainless steel variants. It does not appear to be selling the ceramic Apple Watch Edition.



For those that elected not to or are uninterested in pre-ordering online, Apple Watch Series 2 models launch at Apple retail stores and authorized resellers like Best Buy on September 16. In-store stock will likely be very limited, with customers accepted on a first come, first served basis.

Apple Watch Series 2 models feature a built-in GPS, water resistance up to 50 meters, a faster S2 dual-core processor, and a display that is two times brighter than the original Apple Watch. Series 2 models will come with watchOS 3 preinstalled, while the software will be released as a standalone update on September 13.
