I think LCD would be best as the design is meant to be left on, rather than activated to display the time. If it is LCD though, you would probably need it to be a negative display, with a backlight that can be activated – similar to the negative watch. This would probably make it so the line color between each cell would be lit up when the backlight is activated, which would make for an interesting effect, I think.

I really think tokyoflash needs to make more watches like this (not specifically this one, but other community made concept watches). They are cool and professional looking designs that tell the time in interesting ways, without looking gimmicky.

To tell the truth, what I mean is, the latest few new watches like ‘wasted’, ‘traffic’, ‘changing lanes’, and ‘broke’, while they are undoubtedly cool, they lack the kind of neat and ordered systems that I loved in the more classic designs (like the Denshoku, waku, barcode and pimp watches), and like what is shown here. Sorry to sound negative, but thats just what I think.
