Footnotes
Research by Ted Denton revealed only a few examples of this curious watch. The dial was apparently first designed by a British postmaster, Hill in the 1880's in an attempt to simplify transmitting time in Morse code, when using a coded sequence of letters to represent numerals.
The watch is designed to directly read the letter code from the timepiece. For example, if the letter "B" designates 2:00, then the letters "B F" represent 2:30 and, for one minute intervals, the sequence "B F S" means 2:32.
Never adopted, it is not known how the Marconi Company learned of the dial, suggesting the surviving examples may have been prototypes in an unsuccessful experiment.
