Pretty cool technology.
From the article: " At Baselworld 2005, SEIKO unveiled the world's first ‘Electronic Ink’
watch. It offered an entirely new kind of display which was ultra-thin,
high contrast, and which allowed much higher visibility from a much
wider angle (almost 180 degrees).
In addition, it required a very low level of power
while having a virtually unlimited size of display. This “E-Ink” or EPD
(*Electrophoretic Display) watch excited great interest and won a prize
at the “Grand Prix d’Horlogerie de Genève” award ceremony in autumn
2006.
Since then, this technology has become much more widely
understood and appreciated by consumers, thanks to the increasing
popularity of ‘electronic’ books."
