Better Watch Face Customization
Apple also made great improvements to the watch face customization. In watchOS 7, the customize button you knew was replaced with an Edit button.
Not only that but there are also many tweaks to the overall user interface of the watch face customization. For instance, you’ll have a small color palette on the right of your Apple Watch where you can see which colors you can use.
Finally, the biggest change has to be on the complications. Before you could select the complication you wanted to change and you’d need to scroll to change it, which was a bit hard and annoying. Now, you can select the complication you want to change, and a window will pop up with all the complications you can add. It makes it so much easier to see which complication you want and a small preview of it.
