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

American Speed-Up/Slow-Down Indicators – Set of 3 – Adjustable Timing Mechanisms – Vintage New Old Stock – Limited Supply

This set of 3 American speed-up/slow-down indicators is designed for fine-tuning the accuracy of vintage American clock movements. These adjustable timing mechanisms are typically mounted on the back of clock movements, allowing quick and precise regulation of speed without opening the case or dismantling internal parts.

Each indicator operates by moving a lever or screw: adjusting in one direction speeds up the clock, while the opposite slows it down. Used to counteract natural variations caused by temperature, humidity, and wear, these parts are essential for keeping vintage clocks running on time.
