A very interesting idea...
... in the 18th to early 19th century, there was a "Clock Man" in the Castle and he changed the placement of the weight (distance from the center) on the balance wheel in the clock so that the speed of the hand changed. So, there may be an answer in the "variable inertia moment" so that the the vibration/ beat changes everyday..... Interesting!

Variable-speed hands
I was thinking about the Japanese-style timekeeping over on the AHCI forum: He's implementing the variable-length hours in the obvious way, with a 24-hour face and hour indicator blocks that move around to synchronize with the seasonal hour length, since...
In love with your idea!
without having the faintest clue, except for the cam, of how to realize it technically. That could bring me into the habit of wearing two watches per day (or night) one on either wrist for the normal and one for traditional Japanese timekeeping. The monks...

Still thinking.......
As you said, how to stick a CVT in a watch (and change the ratio twice a day) . Everything I have thought of up 'til now would just take too much power. So I keep thinking............................................... Makes an interesting way to keep the...
I was thinking last night..
and think that if we have an hour-only watch with a jumping hour, there's a way to do it. Build a stack of 3 cams, a usual jump-hour snail (rotating once per hour), a 12 hour wheel, jumps one position to increment the hour and a 1 year wheel which indicat...
Perhaps we could complicate this a bit more?
Can I restate the problem to see if I understand it? Your challenge is this - build a time keeping device where the 12 Hours (or 720 minutes or 8640 seconds) at night are longer or shorter than the 12 hours (etc) in the daytime. The time variation is dete...
Basically...
Though I was assuming this would be tied to a specific longitude and latitude, since it would have to know the time of sunrise and sunset to work at all. A
