The world time complication is a feature that displays the time in different time zones, usually through a subsidiary dial surrounding the main dial. These time zones typically cover 24 cities, often chosen for their political or economic significance prior to the introduction of world time.

Complicated world time watches typically have an inner rotating or fixed bezel that bears the names of different cities or time zones. The inner bezel can be adjusted to align with the desired time zone, thus displaying the corresponding time in that area.
