Abstract

A timing device includes a time display section and a drive unit. The time display section has a dial with a measurement indicator from a zero time position to a maximum measurable time position, and pointers capable of rotating above the dial in a fan-shaped trajectory. The drive unit drives the pointers above the dial from the zero time position to the maximum measurable time position, and stops the pointers above an extra display section in a position past the maximum measurable time after the maximum measurable time has passed.
