 The term "primitive" refers to displays of low resolution where one can discern the individual pixels.Among the many programs and utilities which have been developed for the watch, such as football schedules, weather reports and others, there is also a screen saver which blanks out the display of the watch on the minute or the hour, appropriately called "Screen Saver – Blank".Another application called "Antikythera" emulates some of the functions of the Antikythera mechanism by calculating the phase of the moon.
