Casio released in
August 1998 a special G-Shock and Baby-G series to support the Polar Science
Center of the
Applied Physics Laboratory of the University of Washington, Seattle.
There were 6 G-Shock's and 6 Baby-G versions released. This is the
AW-500NS-3ET. This G-Shock has no Backlight and a bit clumsy control, when
you are used to other G-Shock models. Click on the banner to visit the Polar
Science Center website for more information. Scroll down to see more.
