Jason Snell had this to say when the Series 4 was released:
“The result is that I like lots of aspects of the watch faces on the Series 4, but after more than a week of fiddling with complications and faces, I’ve yet to settle on one that I am comfortable with. [. . .] The circle of the Utility and Infograph watch faces are exactly the same size. There’s no reason that Utility shouldn’t use modern complications. I understand that Apple may have had bigger fish to fry in watchOS 5, but it feels like it’s time for a upgrade and rethink of all the Apple Watch faces.”
There's a really weird design schism in watchOS. I don't think I should really have to dress it down—anyone who owns a Series 4 with watchOS 5 knows this. A lot of the nice and new complications are absent from ‘legacy’ faces, which is a shame given that some of these faces are far nicer than the new ones. Take the Solar face as an example. There is no reason why the current Solar face, on right, can't support a Complication setup like the one I've mocked up here, on left:


This complication class on left already exists for the Breathe face. Why can't the gorgeous Solar face also be functional? This should be a top priority for the Watch team, in my eyes. If they won't allow third party faces, they better be fixing up their own. Sadly, none of the leaks seem to be hinting at this. But who knows—perhaps they know already and are working on cleaning up the gallery. There's a lot of redundancy and mismatch going on, and it really isn't too monumental a task.
