Made me think about the Swiss Railways clock that has the second hand completing the circle in 58.5 seconds; all the clocks on the network then wait for the sync signal from the “master clock". https://en.wikipedia.org/wiki/Swiss_railway_clock

I love those clocks! But from memory, the second hand gets "stuck" at 12 and then when it moves again, the minute hand advances at the same time. On this one, the minute hand jumps forward at the same time that the second hand goes to 12.

The second hand is supposed to go round the clock in 58.5 seconds, and then 'wait' for a synchronisation signal before starting off for the next minute.

Earlier quoted context omitted.

They do for me. Maybe you just need to watch for longer.

It seems to be glitching somehow. The minutes needle jumps once, then gets stuck after that.

Have you watched for more than 5 minutes? Each hand jumps from one Division to the next, increasingly flexing in between jumps. It's working fine for me, and obviously for others, so either there's something odd about your setup, or it's just doing something you don't expect.

I saw somewhere on the internet a clock where the hand of the seconds moves at random irregular intervals, but averages out to 60 moves a minute. Extremely frustrating to watch. Edit: here's a video of it running (somehow the seconds hand runs backwards) https://www.youtube.com/watch?v=HKU-zmNFSxw

The second hand isn't running backwards, the numbers run the wrong way.

Cute, clever!

But the way the minute hand stays pointing to a multiple-of-five-minutes until it Boings! to the next increment is disconcerting.

It looks like it's slow all the time. E.g. 10:29 looks like 10:25 which is more than enough error to look wrong.

Maybe I'd learn to read the bent-hand deflection after a while. But I guess I prefer the clock I have that just points to the right minute all the time.

The animated example in https://en.wikipedia.org/wiki/Swiss_railway_clock#/media/Fil... seems to have the first behavior you mention, it get stuck at 12, minute hand increments and then the second hand starts moving again after the minute hand movement.
