Origins: From Harvard Clock Co. to Boston Clock Company

The roots of the Boston Clock Company trace back to the Harvard Clock Company, established on October 11, 1880, by Joseph H. Eastman, James Gerry, and other Boston clockmakers. Harvard was part of the thriving Massachusetts horology scene that grew from earlier American clock-making traditions. 

On May 29, 1884, the firm reorganized and renamed itself the Boston Clock Company, continuing the legacy of Harvard while refining its identity in the marketplace. The newly formed company was based in Chelsea, Massachusetts (near Boston) and was managed primarily by Joseph H. Eastman. 

Initially, Boston Clock Company produced wall and mantel clocks — often inspired by popular French carriage and regulator styles — featuring balance wheel escapements and distinctive case designs that appealed to late-19th-century American consumers. 

Innovation and Growth: Producing Striking Clocks (1886–1890)

In 1886, Boston Clock Company made a major technological contribution to American horology with its patented tandem wind striking movement — a mechanism allowing a single key to wind both time and strike trains simply by turning in opposite directions. 

This innovation enabled the firm to shift from primarily time-only clocks to striking clocks, which were increasingly desired by customers. Research also suggests the company produced limited ship’s bell style clocks during this period, though surviving examples are rare and often vary significantly in movement design. 

By 1890, Boston Clock Company’s trade catalog featured more than 50 distinct clock models, including regulators, mantel clocks with porcelain dials, and wall clocks in elegant onyx or wood cases — evidence of both design breadth and commercial ambition. 

Decline, Receivership, and Attempts at Revival (1894–1896)

Despite its technical innovations and expanded product range, the Boston Clock Company struggled financially in the mid-1890s. In 1894, the firm failed and was reported in trade journals as being acquired by the Ansonia Clock Company, which continued offering Boston clocks in its catalog for several years afterward. 

In 1895, Joseph H. Eastman attempted a revival by founding the Eastman Clock Company on Everett Street in Chelsea. Though backed with capital and a new factory, this venture lasted only through 1896 before creditors foreclosed and the company dissolved. 

On October 29, 1896, Charles O. Warner acquired the foreclosed property, machinery, and tooling, marking the final winding down of the original Boston Clock Company’s operations. 

Legacy and Collectibility

Although the Boston Clock Company’s lifespan was brief — roughly from 1880 (Harvard) to 1896 (Eastman closure) — its output remains prized by collectors and historians alike. Early Boston clocks stand out today for their tandem wind movements, balance wheel escapements, and distinctive American clock styles that bridged the gap between Connecticut-made movements and French regulator aesthetics. 

The designs and innovations pioneered by Boston Clock Company also helped lay groundwork for future successful American makers, most notably the Chelsea Clock Company — which purchased Boston tooling and continued the marine and striking clock traditions into the 20th century.
