1. DESCRIPTION
Relative to other digital watches, the Casio G-Shock is capable of dramatically more
functionality. For instance, it is capable of tracking location-specific tide levels and moon
phases. Such vastly increased functionality combined with the same interface that was
problematic for a much smaller set of functions leads to some headaches and a surprisingly
complicated instruction manual. In the following, I will discuss three user interface problems
with the Casio G-Shock. These problems are not specific to this particular watch and would
also apply to any digital watch using the same interface.
