Designed by Hironao Tsuboi, this LED watch has no face.
It looks like an ordinary silver segmented bracelet. But telling time is not too difficult on this watch, as the LED-powered hour and minute digits will light up across a few of the segments on this “silver bracelet”.
The LED Faceless Watch measures W-97 x D-81 x H-60 and has 3 distinctive colors to choose; Silver, Black and Ultra marine.
