Chelsea Clock Company offered electric clocks using DC battery power as early as 1908. These battery powered models for automobiles and the Automatic Ship's Bell lasted until the mid 1920s when Chelsea began experimenting with AC power. Chelsea presented their Telechron motored AC clock in Catalog 16 of November 1930. This was unfortunate timing as the depression killed any demand for an expensive new idea. The next catalog in 1931 did not offer any Telechron motored clocks. The few clocks with Telechron motors that are known were made in 1930 and 1931. The continued depression and World War 2 were the death knell of these fine clocks. After WW2 Chelsea did offer the VE (Victory in Europe) bedside electric clock but even this model did not survive the limited demand and was soon eliminated from the line.
