I suppose one could argue that even a manually disciplined clock (e.g.,
analog AA wall clock in the kitchen) is ultimately computer regulated
when flicking the hands while glancing at a cell phone.
The 10,000-year clock is disciplined by the Sun, though for some
functions this is relative to its
The Corpus Clock is entirely mechanical (and analog), isn't it? The
distinctive lighting effects are cleverly designed backlit slits lining
up or blocking the illumination.
On the other hand, the Clock of the Long Now is a mechanical digital

Reminds me of the Corpus Clock https://fanf.dreamwidth.org/96948.html
aka the Chronophage.

Oh, my. That sounds like a crazy project (and I mean that in the
best possible way), but it's not so far from a project I did,
and one I'm thinking

A leap second related story problem.
After visit to USNO years ago I wanted to make a leap second desk clock as a
thank you gift. The idea was to use a standard 32 kHz quartz clock stepper
movement [1] [2] but drive it with a microcontroller such that during a leap
second it slows down for a
