The unusual feature of this clock is the tapered gear controlling the output of the spring barrel to improve the timekeeping.

Known as “fusee” — a name thought to have come from the Latin “fusata” meaning a spindle of thread — this device lessens the power from the fully wound spring and increases as the barrel unwinds, so evening out the torque to the clock train.

The movement is 8-day, pendulum with a single strike on passing the hour. Base: mahogany.
