The watch Arun gave me!

Digital watches need two or three pairs of digits zero through nine and a separator, usually a colon realized as separate segments. Watches supporting 12-hour mode also need an AM/PM indicator, which can be as easy as a dot segment lit or not. Seconds may use smaller segments.
