I tried to google it very hard but it seems blocking, I always end up with tutorials to change the complications and publish it for friends...
What I want to perform is create my own Watch Faces for my Apple Watch, with room for official complications. So I would be able to create my own watch face. Chronology did it, so why wouldn't we? I just don't find the documentation for that.
Please note, I don't want to create a "time-centric" application, I am here talking about real Watch Faces. My goal is to create something where the time only take the place of a small complication, with a custom design of mine, and then I have plenty room for complications from my favorites / personal applications !
This question concerns the Apple Watch (And Watch OS), not WearOS.
Many thanks for your help !
