During January of 1897, the Waltham Clock Company was formed at Waltham, MA. for the manufacture of high-grade tall clock movements and to compete with some of the English and German firms which were importing tall clock movements and clocks in increasing numbers. This firm succeeded the Waltham Electric Clock Company which was dissolved and the manufacture of electric clocks discontinued.

Tall clock offerings increased for the firm during the first decade of the 20th century, dozens of case styles were being offered with several optional movements. By 1915, the best quarter‑ striking movement with three different chime selections played on nine tabular "bells," a moon dial and solid mahogany colonial style case could be purchased for $560.00 retail.

In 1913, the Waltham Clock Company was purchased by the Waltham Watch Company which was wanting to diversify its watchmaking business. The Waltham Clock Company name was continued until 1923 when, during a reorganization of the parent firm, the name Waltham Watch and Clock Company was adopted. This name lasted only about two years when the name Waltham Watch Company was adopted for all operations.

Production of tall clocks declined during the 1920's though more mantel and wall clocks were added to the line. Production of pendulum clocks ceased about the time of the Great Depression, though electric clocks and speedometers were manufactured until about 1940.
