This watch looks designed especially for science geeks, because it displays the time on nixie tubes. For those that don’t know what nixie tubes are, they were used back in 1969 in calculators and are quaint neon display tubes. This watch only requires the flick of the wrist to display the hours, minutes in seconds in a sequence. It’s advantages are that it’s both rugged and water resistant. The Nixie Watch is great somebody that wants to be unique.
