Early Years and History
The Chelsea Clock Company has a rich history that spans over 119 years. The company was established in 1897 in Massachusetts, and its early years were marked by producing high-quality pendulum clocks and marine clocks.
Chelsea Clock Company made numerous product design improvements, many of which it patented. One notable example is the design for a ship's bell clock with a fully encased chime and striking mechanism, patented in 1900.
The company's marine clocks were in high demand, particularly by the United States Navy, which ordered over 100 clocks for its offices throughout the country in 1907 and 1908. This led to the establishment of the Boston Clock Company, a separate brand for clocks and related instruments.
Under the guidance of its founder, Chelsea Clock Company's business grew profitably from 1906 until the late 1920s. However, the company's founder passed away in 1928, and the company was later acquired by William Neagle, who had been hired by the founder 26 years earlier.
