I've just got my Synchronome master clock runniing againg after a spell of 20 or so years in storage. It was clunking away fine until we decorated in our living room but after we finished it was banis

Afternoon all! I recently achieved perfect time keeping with my Synchronome master clock thanks to the weight tray and some calibration weights. I found a nice set of gram weights that my father had s

I am wanting to connect my MK1 Synchronome to a 4 zone Synchronome Distribution Board. I have found one hand sketched diagram on the web but this does not seem to tally with my board wiring. Were ther

I attach some photographs of a weight tray and advance mechanism on one of my synchronomes. The clever little pulley and weight setup allows the clock to be advanced by lowering the weight onto the tr

Hello, I have at last got round to getting my Synchronome running again and as usual have had trouble with double pulsing!! Behaving itself when I left it! Reading Bob Miles' book (2021 edition) I not

This was recently mentioned as a possible aid to pendulum weight analysis Does anybody have experience of using these machines? Does anybody know of a cost effective service in the UK? I was thinking

A EUREKA MOMENT. This morning my head came up with a convincing hypothesis to a question that I have had unanswered for several years which was “Why do mark 4 and earlier type 36 clocks have the advan
