A watch's main purpose is to tell time. The watch has been a successful tool for a very long time.
The main reasons for this are:

a.) Comfort - a watch fits around the arm and is unobtrusive and lightweight.
b.) Availability - since it is worn around the arm, it is always with the user.
c.) Luxury - a watch is thought of as jewelry, instead of as a tool.
d.) Quickness - a watch's data is laid out in an easily digestible format. Typically, a user can gain the necessary data just from a quick glance.

The FLORA attempts to maintain these four qualities. Since the FLORA's design is built upon a typical watch, the first three qualities are already built into the design. The fourth - quickness, is achieved through the use of colored light and simple text as a way to display location data.
