I recently had the questionable pleasure of restoring a Eureka clock. These clocks are very desirable among a certain class of collector, I count myself among them, however their rarity and price makes them a little luxury.

If you don’t know Eureka clocks, the picture of the clock in question will show you the main feature of interest to the owner – the oversize balance wheel. In this case, the balance is behind the dial in a 4-glass timber framed case. Most Eureka clocks have a rate of 1.33333 seconds per beat, but this is one of the more unusual 1.5 second rate. They run on a 1.5volt battery – originally one of those big cylindrical batteries that readers of a certain age will remember from their high school science class days.
