Tokyoflash Japan has introduced a new watch that looks like something that Al would have worn on Quantum Leap. The Kisai Neutron watch has “sub-surface” LED bars that display the time by either pulsing through the four digits and colon or by having them roll up and off the display. The lights can be set to be always on, and because the Neutron has a motion sensor, you active the actual time display by a twist of your wrist. It uses light as a decoration and light as a timepiece displaying time and date. It has a plastic and stainless case and adjustable stainless steel band, and it has a USB-chargeable battery inside. It’s available with a black or gunmetal band with your choice of red, white, or blue LEDs or in gold with red or white LEDs. As always, Tokyoflash Japan has introduced the watch at a limited-time special price. As of the time this is posted, you have about 13 hours (until Thursday, August 1, 2013 at 12:00 noon Japan time) to purchase the Kisai Neutron for $139.
