Simple can be "unique" sometimes. Designer Lim Sze Tat concept cell phone and watch are simple yet they stand-out. The Dark Label Retroxis phone [picture here] is enclosed in a polished polycarbonate, it features OLED displays which silently disappear after the phone is inactive for sometime, this gives the phone a sleek look. The Dark Label Revol time piece [picture here] spots a rotating disc in place of the conventional hour and minute hands. It's also enclosed in the light, yet tough polished polycarbonate. I am not sure when we can expect this concepts to hit the market, if they go into production.
