    Dear Les,

    I have reached this page after reading your book, in which I saw an illustration of the Japanese “Omron” motor that drives this timepiece.

    Superficially, it resembles the Warren motors used in Everett Edgcumbe “Synclock” clocks, i.e. a sealed rotor and reduction gearbox assembly.

    Is this actually the case, please?

    Many thanks,

    Nick Arnold (Oxford).

      Dear Nick
      The motors are indeed very similar. The point is that Warren patents prevented the use of a sealed rotor and reduction gearbox, and the use of shaded pole self starting, by other early manufacturers. These patents have expired so the features can now be used freely.

      Regards

      Les

    Dear Les,

    That’s interesting to know, many thanks for your speedy reply (which I’ve only just found, as the auto notification by e-mail didn’t get through to me – spam filter, maybe?).

    Thanks for a great book, which is now in my bookcase with my ever-increasing collection of electric clock literature. It’s so nice to see people taking an interest in these fascinating devices again.

    Nick.
