If you’re bored of the default watch faces on your shiny new Apple Watch Ultra or Series 8, and want to unlock the endless options made possible by the free Clockology app, you’ve come to the right place.

The only small downside at the moment is that either existing clock faces will need to be updated and reworked to fit the new, larger 49mm screen size of the Ultra. This means our curated list of “geek approved” faces might run a little small on the Ultra at the moment. But still, no harm giving them a go, or trying them out on your new Watch Series 8.
