Re: Wiring connections in early master clocks

Hi Stephen,
Could you tell me the serial number of your Synchronome?
I have one with an identical latch, but it must have been sold
as a bare movement, because it was re-cased and has no serial number.
Somewhere there is a graph of number vs date so I could then date my clock,
thanks,
Neville Michie

Yes your clock looks great.
There is a company here in Belfast which makes old-style braided cable in about 70 colours. I have bought it in the past, and it is excellent:

Click on the 0.5sqmm ones, and then look at the colour chart.

The same stuff is also available online from many sellers. Do a Google search for "vintage braided fabric flex cable", and you will find loads.

I recently restored a Synchronome clock from about 1920 - post WW1 austerity model. Complete restoration of movement, including light blasting and repainting of base-plate, as the whole thing was rusty and had been dreadfully repainted in the past, so there was nothing else for it. It had also lost all of its original wiring, so I decided to go to town with the wiring, and yellow is my wife's favourite colour (this way she let's me have it in the kitchen!!). Not one for the purists, sorry, but everything has been restored just as it should be, and the wiring could easily be changed for something more understated if required! See below...

Also, somebody mentioned the little wire which disappears behind the bottom coil. This clock has exactly the same thing. I found that this little wire actually goes to a secondary small coil behind the base-plate, which is connected in parallel with the main coils. The function of this wasn't really clear to me - maybe some sort of early attempt at spark-quenching?
