The O'Hara Waltham Dial factory was a three-story brick industrial building erected in 1897 at 74 Rumford Avenue in Waltham, Massachusetts, by Daniel O'Hara to house his clock-face manufacturing company, a spinoff from the Waltham Watch Company. Designed in the Italianate style, the structure featured distinctive corner towers with paneled brick surfaces added in the early 1900s. After O'Hara's company ceased operations in the late 1950s, the facility was repurposed for manufacturing traffic signals and luggage. Listed on the National Register of Historic Places in 1989, the building deteriorated significantly and was deemed beyond repair; it was demolished in June 2019, leaving only portions of the original foundations.
