James McMillan, (May 12, 1838 – August 10, 1902), was a United States Senator. A dominant figure in the Michigan Republican party, he was elected as a Republican to the United States Senate and served from 1889 until his death in 1902.

Born in Hamilton, Ontario, he moved at an early age to Detroit, Michigan, and began investing in The Detroit & Milwaukee Railway and the Michigan Car Company, which was at one time the largest in the United States. A director of several Detroit banks, owner of the Detroit and Cleveland Steam Navigation Co., and the Detroit Transportation Co., he contributed significantly to hospitals and shipbuilding companies.

The McMillan Plan is a comprehensive planning structure for the development of the core and park system of Washington D.C., the United States capital. Formed in 1902 by the Senate Park Commission, it is widely acknowledged as the McMillan Commission after its chairman and sponsor of legislation.

The McMillan Plan, which was presented to the public and President Theodore Roosevelt in January, 1902, continues to guide urban planning in and around Washington, D.C.

The dial of this watch has an enamel portrait of a child, thought to be James McMillan's first son, William Charles McMillan, and the hinged case back with monogram J. Mc. M. for James McMillan. To the best of our knowledge this watch has never before been offered in public.
