A new set of Apple Watch models could be introduced as early as this coming fall. Apple will reportedly come out with three new watches. KGI Securities analyst Ming-Chi Kuo claims there will be three new models with different cases. Apple is already set to release Apple Watches in gold, rose gold, stainless steel, and aluminum.

Kuo has not said which materials could be used with the new Apple Watch cases. Though, at least one other report from the Wall Street Journal suggested Apple was working on a platinum case.

If Apple does update the Apple Watch line in the fall, it will be doing so much faster than usual.
