ITR Master Clock Correcting Time For Daylight Saving

Just for fun I recorded the daylight saving transition of one of my master clocks

This is an ITR (International Time Recording) Model 26/8/5 master clock
It is mains powered with battery back up
The movement is the same as was used in the IBM, ITR and Simplex pendulum master clocks.
It has a 30 RPM motor that simulates the pendulum.
The movement is spring driven which is maintained by a 1 RPM motor
In the event of a power failure, a small DC motor runs the clock.
There is a pulse accumulator fitted to remember the missed impulses
When the power is restored the clock corrects the slaves automatically

This clock will run both synch wired hourly correction and standard hourly supervised slaves

Well…

YOU took the time to watch this video AND make a comment on it

SO maybe YOUR life must be without major events

There are a lot of people who are interested in this old technology and learn from it

You are clearly an imbecile or maybe your Idiot phone hasn’t got an “app” that has told you this yet

LOVE IT! You got yours to actually work. I had an IBM 97-1 I never could figure out.

Had to sell it. I am envious!

I have a T&N German railways slave clock. Do you know of a cost-effective way to power and drive it?
