Index (Regulator) is a type of watch face that displays the time with two or more hands (hour, minute and sometimes seconds) that are all connected to separate dials or “regulators”. Typically, each hand is connected to its own dial and moves independently from the other hands. The dials are arranged in a linear fashion, usually from left to right, with the hour hand on the left and the minute hand on the right. This type of watch design is popular for its visual complexity and for its ability to display multiple time-telling indicators in a single, compact piece.
