here arethe info i gathered:
The watch is designed by naoto fukasawa for IDEO.
Heres more background on it
2001 at NTT InterCommunication
Centre (ICC) in the Tokyo Opera City
Tower, Fukasawa showcased, with
IDEO, the LED Watch. A small rectangle
block formed from co-injection
moulded plastic with an embedded
light-emitting diode (LED) panel, this
wristwatch rests veiled within a blank
slab. It isn’t until pressure is applied to a
switch hidden in the band that numbers
become illuminated, stacked with the
numeric hour over the minute.
But it's not available anywhere , maybe watch ebay or ask ideo:
