Warren Telechron Co., Ashland, Mass., "Warren B. Master Clock", (No. 127 Frequency Clock) in an oak case with silvered dial, 110v motor combined with quality spring movement. Spring movement moves the center hand backwards; electric movement moves it forward, serial #1036 the case has been refinished and there is dent of the bottom of bezel. The dial is in excellent condition. 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.
