Footnotes

  • An unusual feature of this particular watch is the perpetual calendar on the inside caseback enabling one to determine the day and date for any particular month in any particular year. This is achieved by means of the dominical letters. These letters a-g correspond with the seven days in the week and each year has its own letter except for leap years which have two, one for days up till the 29th February and the other for the rest of the year.

    This watch was previously part of the Time Museum Collection in Rockford Illinois.
