This is a nurse's watch. It is mainly used by nurses. The dial is inverted, making it easy to see the time, and the numbers are highly visible and easy to check. It's a clip-on type, so it's easy to attach to a pocket and doesn't get in the way. Also, it can be used by a wide range of people, from children to the elderly. It can be used on belts, skirts, aprons, and other small places.
