Wall clocks

Buy that clock and change the innards - I think they all have a standard size mechanism - no guarantee though
You can get a radio controlled mechanism for about £12 on ebay
It's a bit of a faff, but shouldn't take more than 20 mins to do
Be very careful when snapping on the hands
 
you want an atomic wall clock

1.​


  • Most "atomic clocks" sold to consumers aren't actual atomic clocks, but radio-controlled clocks.
  • These synchronize to atomic time by receiving signals from national time stations.

In the UK:​


  • The signal comes from MSF, a 60 kHz radio time signal broadcast from Anthorn, Cumbria.
  • It transmits UK civil time (UTC+1 in summer, UTC in winter).
  • Coverage is reliable across most of the UK.

⚙️ What You Need:​


  • A radio-controlled clock or device that supports the MSF 60 kHz signal.
  • Most UK-sold atomic wall clocks, watches, and weather stations already support this.
I didn’t even know this was a thing - every day is educational on OcUK :-D
 

those are the people who make the clocks for the swiss railroad.

Iconic industrial design with WiFi connectivity.
The NEW Mondaine stop2go WiFi Clock provides an easier user experience thanks to its one-time setup through WiFi. It has the functionality of the original Swiss Railways Clock – Its sweeping iconic red second hand temporarily stops for 2 seconds when it reaches 12, so that the minute hand can gracefully jump to the next minute. The clock also features the renown sweeping second hand.

Does this even work on a standard AA driven mechanism analogue clock?


I would say if it was a digital wifi clock you could find one that supports NTP

however, i have never heard of a self adjusting timezone analogue clock
 
In my experience the classic design braun (also alarm) clock I have is sufficiently accurate that don't need an automatic update, and the bi-annual change isn't onerous

Not sure I'd want the distraction of a large face and sweeping second hand though, especially in living room, which will probably detract from battery life;
I will use my phone in the kitchen if I am timing an egg, anyway, there is always the clock on the uwave & oven too.

So if it stops for 2 seconds every minute... does it lose a minute every half hour, or is it near permanently slightly wrong to lead/trail those two seconds?

Either would annoy me on some level (one more than the other), but not as much as needing an iPhone to set it up. I'm also dubious/curious as to the battery life if it's connected to WiFi.

I remember our secondary school installing radio controlled clocks (this would have been around 99-2000), much hilarity ensued as the spun endlessly trying to get a signal for a couple of days while we were pushing it a bit with lesson/lunch times and winding the teachers up (yes, my school life was sufficiently dull that I remember that happening 25 years ago :) )
 
Yep it's amazing what AI generated content people are happy to provide :(

I worked at NPL for 11 months, where they have one of the 11 6 atomic clocks worldwide. This machine isn't a clock at all, but rather a machine that fires atoms back and forth and measures their travel time. It is synced with the other 10 worldwide and if any of them go out of sync, it flags with their monitoring system. It's virtually impossible for all 11 to fail due to the amount of redundancy on each site. The time is then broadcast via rather primitive radio signals to these "radio controlled clocks" which then automatically adjust.

It's a fascinating system, some of the most advanced technologies in the world maintaining our time, and broadcasting it via a system that's over a century old.

you don't need another translation do you ?

I guess chatgpt can't access video resources yet but the under-hand lume on the mondaine stop2go watches is cool

This genuinely sounds badass, for a clock! Overkill, but still badass, haha!
