Apple has added four new Apple Watch Guided Tour videos to its website, giving users a general overview of how to operate the watch, in addition to closer looks at Messages, Faces and Digital Touch features on the upcoming device. Other instructional videos for features like Siri, Phone Calls, Music, Apple Pay and Maps are listed as “coming soon.” The videos emphasize how the Apple Watch augments some functions of a user’s iPhone, and the basics of how to customize the look and information displayed on the watch face. Apple begins accepting pre-orders for the Apple Watch at 12:01 a.m. Pacific Time this Friday, April 10.
