The three-story brick structure was built in 1897 by Daniel O'Hara, and housed his company, a spinoff from the Waltham Watch Company which specialized in the manufacture of a variety of clock faces.

The building had distinctive corner towers with paneled brick surfaces, although these were a later (early 1900s) addition.

O'Hara's company operated until the late 1950s; the facility was then used in the manufacture of traffic signals and luggage.

[1] On April 5, 2019, the city of Waltham issued a Notice of Unsafe Structure for the building.
