Notes

The American Perpetual Calendar The linear digital calendar or so-called ?American calendar? is a calendar in which the date is displayed in a single linear aperture allowing for a clearly legible 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 once again after the second World War.
