Howard & Co. was a clock and watch company formed by Edward Howard and Charles Rice in 1858, after the demise of the Boston Watch Company. The pair acquired some of the material and watches in progress, based upon a lien against the defunct company held by Rice, but they were unable to buy the existing factory or machinery, so they moved to Roxbury. Soon afterwards, Howard bought out Rice's interest and thereafter concentrated on high quality watches based on his own unique designs and eccentric production methods. E. Howard & Co. produced high grade watches, regulators, and marine clocks. Regular watch making operations ceased in 1903, when the Howard name in association with watches was sold to the Keystone Watch Case Co. Keystone purchased the defunct US Watch Co. factory building in Waltham, Massachusetts. Keystone manufactured watches at the location signed "E. Howard Watch Co." These watches were of new designs and unlike those of the original Howard Company. Clocks were manufactured at Roxbury, a section of Boston, but in the early 1930s those operations were also moved to Waltham, Massachusetts. A very small number of pre-existing Howard watches were finished in the Howard clock factory between 1903 and 1927.
