    I recently acquired a Poole electromagnetic clock, Model Executive #5, SN 2366, which dates it to 1927. I usually collect older, purely mechanical clocks, but I found its principle of working quite interesting. Usually, the movement drives the pendulum but here, the pendulum drives the movement. In order to keep the pendulum moving it gets a little push by a gravity lever from time to time. The gravity lever is pulled back up by a battery driven electromagnet immediately after giving the push to the pendulum. The clock is supposed to run about a year on a set of batteries with timekeeping of within a minute a month. I'm currently adjusting the speed to verify this claim.

    The clock was in poor condition when I got it. If you are interested in the restoration, see here:

    Very cool. I'm not a fan of electric, but this is an exception. It looks great too.

    Love electromagnetic, and yours is especially nice with the seconds bit. It is an intriguing combination to have a clock battery powered, but turning wheels and a swinging pendulum that satisfies the fondness for mechanical movements.

    Very nice, I have the exact clock, also marked "Morse Chain Co. Ithaca, NY" on the dial, and a second one which is minus the globe. I think the years run on a set of batteries is probably about right. I like the clocks, but if one is accustomed to hearing clocks "tick", its little disconcerting to hear a "ca-chunk" every minute or so.

    That is true! I'm just getting used to the "ca-chunk" (hopefully).

    If you are looking for a fitting globe, Timesavers carries them.
