Numerals are numbers that are used as markings on a watch face to indicate the time. They can be either Roman (I, II, III, IV, etc.) or Arabic (1, 2, 3, 4, etc.). Numerals are often used in conjunction with markers, such as dots or lines, to help the wearer read the time quickly and accurately. They usually correspond to the hours of the day, although some watches feature 24-hour numerals. Numerals are often used in combination with a second hand or subdial to create a more detailed time reading.
