I'm working on a Roman Empire clock along the same lines, but mine counts time according to the Roman Empire tradition. So daylight is divided evenly by twelve hours, starting from visible sunrise until visible sunset. So in the winter, the daytime "hours" are about 45 min long at my latitude, and in the summer, the daytime "hours" are about 75 min long.
I made mine so I could pray the hours (first hour, third hour, sixth hour, ninth hour), but I wanted to reckon the time for my current location, tied to the solar day, instead of linear time. It's been a fun project. I have it working on my phone with notifications, and the next step is to build it with an e-ink display and gps so that you can use it while traveling to change to your location.
Neat! I've got a similar setup for the hours, though I use normal 24-hours and just adjust the start/end times by relation to current dawn/dusk. I'd love to get it on a clock but alas for now it lives as a Home Assistant automation, playing chimes whenever the hour changes. You wouldn't happen to have a repo for your version would you?
I learned about the hours through the game Pentiment; you may enjoy the clock face used in it to tell in game time: https://pentiment-clock.vercel.app/ .
I've always thought that a 24 hour dial would be better to understand where the sun is as the hour hand will point to its position around the earth relative to you

It reminds me of some similar things in the watch world:
- Yes Watches makes hybrid analog/digital watches with 24 hour dials and an inner LCD screen for daylight and other astronomical indicators: https://yeswatch.com/wrist-watch/worldwatch/our-story.html
- The Krayon Anywhere has a mechanical sunrise-sunset complication: https://www.hodinkee.com/articles/krayon-anywhere-universal-...
- Some Pebble watchfaces, e.g. Halcyon: https://apps.repebble.com/halcyon_67cb1c5fb7a02301b9a6e415
I'd also check out Celestial Noon for an aesthetic Pebble one. You lose some info from halcyon but I like the moon phases
