    Good Morning Les
    You obviously have a wide knowledge of Smiths Clocks and Watches Does this include time switches and, if so, would you be prepared to help me to learn more about an example that I recently acquired, please?
    I was intrigued to see the reference to flexagons. I tried to remember where I first came across them and I think it must have been in Rouse Ball’s book.
    Kind regards Alan Cox

    Alan, I know of two Smith time switches. One is the Smith ‘Prestwick’ clock, date 1950, which is intended to turn a radio on and off to act as an alarm. This is illustrated on my website. The other is a central heating controller which was in a house we lived in from 1973 to 1982. This was fitted with a self starting Smith Bijou movement which had the unfortunate habit of sometimes running backwards following a power interruption.
