Seth Thomas Clock Company began manufacturing tower clocks in 1872, and these clocks came to be regarded as examples of high-quality workmanship, ingenious mechanical achievement, and an architecturally important fingerprint of the past. In 1883, R. W Hill of Waterbury, CT, supervised the planning and construction of Thomaston's Town Hall, whose Seth Thomas tower clock helped convey artistic creativity and engineering ingenuity while giving the building a symbolic identity that permanently altered Thomaston's appearance. In 1836, Seth Thomas donated the land for the first Congregational Church and, as an active parishioner, contributed substantially to its planning and construction; its tower clock originally had a wood movement mechanism installed by Eli Terry, and the present brass movement was installed in 1890 before being moved to the church's lobby in 1980 for easier maintenance and viewing. In 1915, the last Seth Thomas Building was constructed, and its imposing tower clock crowned the building as the headquarters of the Seth Thomas Clock Company, reinforcing the building's identity and emphasizing its clock-manufacturing purpose.
