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 !
It is not possible. Apple does not offer a way to do this.
From the documentation:
4.2.4 Apple Watch apps that appear to be a watch face are confusing, because people will expect them to work with device features such as swipes, notifications, and third-party complications. Creative ways of expressing time as an app interface is great (say, a tide clock for surfers), but if your app comes too close to resembling a watch face, we will reject it.
