Set of 3 American Speed-Up/Slow-Down Indicators for Vintage Clocks-CLOSEOUT

An American speed-up/slow-down indicator is a small, adjustable mechanism found on the back side of certain American clock movements. It allows the user to fine-tune the clock’s timekeeping by adjusting the speed at which the clock runs.

Typically, it has a lever or screw mechanism connected to the pendulum or escapement. Moving the lever or turning the screw in one direction will speed up the clock, making it run faster, while adjusting it in the opposite direction will slow it down. This adjustment feature is essential for achieving accurate timekeeping, as factors like temperature, humidity, and wear can affect the clock’s pace over time.

These indicators are often found on vintage American clocks, allowing easy access for clock owners to make precise timing adjustments without needing to open up the clock case or dismantle parts.
