A 24 hour watch is a wristwatch with an hour hand that rotates 360° every 24 hours. This type of watch is especially useful for airplane pilots, astronauts, members of the military, or anyone who uses a 24-hour clock.
A 24 hour watch with multiple hour hands or a rotating bezel is particularly useful for displaying the time in multiple time zones.
Most (but not all) digital watches can be set to show the time in 24-hour format.
