date aperture. A date aperture is a cut out section in the face of a watch or clock, displaying the day of the month.
baton numerals. A watch that instead of displaying numerals on the face, displays a marker in the form of a baton, or lower case letter "L". Since the baton-like marks are not numerals, the feature is also called baton markers, baton indexes and baton indicators.
