Huh, I built a 24 hour clock as part of this mini project:

Notably, after the initial page load I don't use any JS to update the hand positions. It's entirely static SVG elements.

Broadcast radio people are _obsessed_ with sweep second hands, since it's how they all learned to time their announcements to end right as the next program segment begins.
If you sold a cheap tablet that did nothing but that, and synced to NTP with a programmable display offset (some stations run 5 seconds ahead of real time to deal with encoder delay, for instance), station managers would beat a path to your door.
