There is something nostalgic, nerdy, and, dare I say, classy about this vacuum tube clock. Pedestrians might think that your retro clock is powered by bluish-green LEDs, but you and your nerdy friends will know that 16-segmented tubular vacuum fluorescent displays really produce the display. The ebay auction only has 10 hours left so if you have $152 to spare, you can own this extremely rare and extremely badass clock.
