I'm interested in any info about this clock and any idea its value for insurance purposes. I believe it was in a lighthouse and controlled the flashing beacon. It runs 6-7 days on a wind.

    Hi Snoopyfriend.

    Very nice piece of history.

    Your clock's case looks like a Seth Thomas Regulator No. 71 that was possibly adapted by the Geophysical Instrument Co. of Washington, D.C. for the lighthouse application you mention. That would be my guess.

    The Seth Thomas Regulator No 71 was from circa 1939 through 1948. It used the high grade, 8-day weight time movement Seth Thomas No. 68 regulated to 60 beats per minute with large keystone shaped plates, polished steel cut pinions, Graham dead-beat escapement, sapphire jeweled pallets and maintaining power.

    The S.T. Regulator No. 71 case measures 60 inches high and 18 inches wide with a 13 inch dial.

    Are those your clock's measurements? After all of that, I sincerely hope so! :)

    Thanks for sharing!

    You're very welcome Snoopyfriend! This was a seriously accurate clock for its time doing some seriously important work. I was pretty sure that NWClocks would really enjoy your post. He posted another Seth Thomas mechanical/electrical application. If you get a few moments check out his O.B. McCclintock Bank Clock at:

    and http://www.collectorsweekly.com/stories/49141-1918-o-b-mcclintock-bank-clock-another-v?in=user

    Thanks again for posting your clock!

    That's an incredible clock, I have just come into possession of one exactly like it.
    I would love to be able to compare notes.
    Are there any others around ??
    Do you have any history on these clocks. Thank you

    Unfortunately, I have no addition info. I inherited the clock. I was told that it came from a lighthouse.

    Thanks anyway Jerry.
    I am looking into joining the national association of watch and clock collectors (NAWCC)
    they have a chapter that meets not far from where I live and see if they have any info on it.
    I would love to see some more pics of your clock, specifically what the inside of the second dial area looks like.
