An auxiliary dial is an additional dial or subdial found on a watch face, usually positioned at the 3 o’clock, 6 o’clock, 9 o’clock and 12 o’clock positions. Auxiliary dials are used to display various types of information such as elapsed time, the date, the day of the week, and power reserve. Some watches also feature a moon phase indicator or a temperature gauge. Auxiliary dials are often highlighted with eye-catching colors, textures and/or patterns to make them stand out from the rest of the watch face.
