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 widely used by people of all ages, from children to the elderly. It can be used on belts, skirts, aprons, and other small places.
