The Biohazard Watch ($138) by TokyoFlash is another one of those watches that can't be read by the uninitiated, but this one takes that gag a step further, pretending to probe for alien DNA and displaying a threat level of possible alien invasion.
It's made of stainless steel, and actually shows you the time and date if you know how to read it. Its website calls it "One of the strangest watch [sic] in the World." Indeed.
