There are several good reasons to own a 24-hour watch. First, they’re very cool, and a must-have for the serious watch collector. If you have an interest in horology, you know that the sundial, technically the world’s oldest way to track the time of day, had a 24-hour interface, there were just no mechanical parts.
Early clocks from the Middle Ages also had a 24-hour display and were either marked I-XII twice or I-XXIV all the way around.
A 24-hour watch can also be much more than a collector’s item or objet d’intérêt. Scientists and researchers working long hours in windowless labs, frequent world travelers, pilots, and military personnel are people who may find the 24-hour watch is more practical than a traditional 12-hour watch.
