Just a small point: WW stands for Webster Whitcomb, the tooling genius
behind the American Watch Company, Waltham. I very much doubt that
Mr. Whitcomb ever designed or made anything to metric standards.

On this subject, I was reading tonight in the Moore book, that John
Quincy Adams, as secretary of state in 1821 was to propose a system of
uniform weights and measures. While admiring the "uniformity,
precision, and 'significancy'" of the French system, He recommended to
congress adherence to the English system with no innovation.
