Seth Thomas Oak Kitchen Clock with 89E Movement

March 27, 2008 | By | 1 Reply More

I overhauled the movement of this clock recently. One of the teeth on the escape wheel was too short, so I inserted a new tooth.

Both mainsprings are original Seth Thomas mainsprings that measure 0.0165 inch thick. The strike speed is adequate, but I wouldn’t want the mainspring to be much weaker. The pendulum takes a fantastic swing, about three times the escape arc. The time mainspring could be quite a bit weaker and still have plenty of power.

This clock appears similar to the College Series “New York” with a different base and glass. It is also very similar to one of the “Capitol” series with a different base and glass.

    Hi, My Grandmother’s 298A, having a movement 98E is in need of work on the chime spring wind/hold ratchet. It has a few broken down teeth so slips and will not hold when winding. I think I need to replace it. I don’t know where to get the parts. Can you help?

    thanks,
    tim
