Roman Numerals are a type of numbering system used in watches and other timepieces. It consists of seven symbols, which represent the numbers 1-7. The numerals are written in a clockwise direction, starting with the number one at the top. The numerals are made up of large and small lines, and sometimes different symbols, such as crosses or other shapes. Roman Numerals are often used to indicate the hour on a clock face, with the larger numerals representing the hours, and the smaller numerals representing the minutes. They are also used to indicate the year on a calendar, with the larger numerals representing the century and the smaller numerals representing the year within the century. Roman Numerals are a timeless and classic way of displaying time, and are still used today on many watches and clocks.
