Are a complication that displays time in a unique way. After 60 minutes, the hour digits jump directly to the next hour. This jump is displayed on a sub-dial or window within the main watch dial, instead of using a traditional hour hand. This complication can also be displayed digitally on a dedicated small screen.

The mechanism of jumping hour watches typically includes a sub-dial or an aperture with hour numerals. When the current hour ends and the minutes reach 60, the mechanism swiftly moves the hour digit to the next hour, creating a sudden jump on the new hour. This mechanism provides a distinctive and accurate way of displaying time. Jumping hour complications are available in both mechanical and quartz watches.
