US Military Stromberg 24 Hour (Slave) Clock from EBoat-This is a beauty! This is a very large clock. It measures 17 inches (43.18cm) in diameter and weighs just over 6 lbs (7.2kg). The face shows the time in 24 increments. The red minute hand looks great against the white face, with black and white hands. The body of the clock has been painted in a nice barn red, almost burgundy color. This is a very interesting clock, this would be considered a “slave” clock which means that it would be powered by a self-winding “master” clock. The partner or self-winding clocks that I have seen while doing research are usually a longer cased clock with a pendulum setup. This wall clock would attach to the cased clock with a long cord. Along this cord may be attached other time keeping devices, like punch clock for your timecard.
The Stromberg company made time keeping equipment for many of the largest companies, like Kodak, and General Electric. This clock was part of the time keeping system for Electric Boat of Groton Connecticut during WWII. This would have been part of a time keeping system, with a master self-winding clock, running all the time keeping devices like punch clocks etc. This particular clock has been modified to run on an electric cord, so it is not dependent on its master clock. We have tested the clock, and it actually works! small knob that allows you to change the time is in place. This clock is in excellent condition. Extra shipping may apply due to its large size. We cannot guarantee the functionality of this clock, we know it was working in our shop, but we are selling it as a historical collectible and display piece.
