Boston Clock Company of Boston, Massachusetts.

The Boston Clock Company was organized by Joseph H. Eastman, James Gerry, and others on May 29, 1884. It was actually located in Chelsea, Mass. This company was formed as the successor to Joseph H. Eastman's Harvard Clock Company 1880-1884. Joseph H. Eastman became the manager of this new firm. This company failed in 1895, and in March of the same year, Joseph Eastman and others tried to revive it as the Eastman Clock Company. This new firm lasted only one year and eventually became the Chelsea Clock Co. in 1897.

The Boston Clock Company manufactured clocks predominately in the style of various crystal regulators, carriage clocks, and other mantel clocks in marble cases. These clocks often featured a compensating balance wheel spring-powered movement. A small number of weight-driven wall clocks were also produced. Most of which were similar in form to the Howard model No., 5 & No., 70 and the Chelsea No., 1.

Boston Clock Company clocks were sold through salesrooms that included Smith & Patterson in Boston, G. S. Lovell & Co in Philadelphia and Wm. H. Atwater in New York.
