During the 1920s and 1930s, jump hour watches were not popular. There production was low, and are therefore today considered quite rare.  Jump hour models substitute the hour hand with an underdial hour disk with numerals 1 through 12. When the minutes advance from 59 to 0 at the beginning of a new hour, the hour disk rotates one increment so the new hour is displayed through the aperture. Rather than progressing over the course of 60 minutes as in the analog display, the hour indication 'jumps' at the last minute of the hour, as suggested by the description.

In 1926, Breguet patented the design of a watch with jumping hours and a revolving dial. With this new design, the central portion of the dial revolves fully every hour, so that the minutes are indicated by the arrow. As the aperture for hour is located at the tip of the arrow, and thus circumnavigates the dial, this feature is known as a 'wandering' hour.
