Notes

The American Calendar
The linear digital calendar or so-called ?American calendar? is a calendar in which the date is displayed in a single aperture allowing for a clear dial which could be read at a glance. This type of display was invented in the early Art Deco period and is most often found in watches destined for the Anglo-American market. This kind of calendar became popular after the second World War.
