The new Apple Watch Series 7 will be available starting October 15, Apple announced today. Online orders will begin this Friday, October 8.

Specifically, those prerelease orders will start at 5 am PDT, one week before the watch hits Apple's brick-and-mortar stores globally. In most cases, preordered Apple devices show up at your door no earlier than the same day that they arrive on store shelves.
