Warren Telechron Co., Ashland, Mass, C. 1925, "Warren 'B' Master Clock", (No. 127 Frequency Clock), in a walnut case, and silvered dial, 110v motor combined with quality spring mov't. Spring mov't moves the center hand backwards; electric mov't moves it forward. Cord was disconnected after checking. It is inside case. Note that you should attach cord and just plug it in; there is NO need to ever wind it again. An additional note is if you stop the pendulum and leave the electric motor running, it can strip off the 'scape teeth {something has to give}. Walnut case is refinished; balance is original and in excellent condition. We ran this to be sure it worked. If the power company is producing 60 cycles per second, and the clock movement is wound and running, the large hand stays up on zero. The console operator at a power station is able to increase or decrease his cycle output to keep the hand on zero. Henry Warren's invention and application of this concept was revolutionary, and initially not well received.....most power companies asked 'Who cares about accurate time?' However by 1925 most operators had realized that by standardizing their output, they could not only tout the use of 110v electric clocks, but could sell or share their power with neighboring companies without fear of a current conflict.
