I am not sure how to put this, but shouldn't it be < Apple Watch > < _____ Edition >?
In my understanding, it is usually product followed by edition, and something to indicate what edition it is. For example, Collector's Edition, Special Edition, Limited Edition, Deluxe Edition.
Using < Apple Watch > < Series 2/3/4 > as example, Apple Watch Edition is like saying Apple Watch Series. What series?
Edited for context/clarity: Apple Watch Edition was announced with the first Apple Watch introduction. You can refer to Apple Watch, Apple Watch Sport, and Apple Watch Edition here: https://web.archive.org/web/20150101174240/https://www.apple.com/watch
This website (https://www.imore.com/apple-watch-edition) has the full list of the original Apple Watch Edition collection, and when Apple added Ceramic into the collection, notice how the same website calls it "Ceramic Edition" (https://www.imore.com/apple-watch-3-edition).
In my understanding it has always been "something Edition", so when I first came across Apple Watch Edition, that something is missing and I always feel incomplete reading it, thus my original question.
However, having revisited the original archived Apple website now made me realize they were referred as "collection", as in Apple Watch Edition collection. Used with word "collection", it does make more sense to me. You have the Sport collection, as well as the Edition collection.
