There's no shortage of retro clocks using those gorgeous nixie tubes, but this one's different. It mixes the 60s-era Eastern European IN-14 time-telling tubes with a serial GPS receiver that keeps its accuracy rock-solid.

In addition to that modern wizardry, it also incorporates clever tube-saving features, such as programmable on-and-off times, along with a routine that displays a scrolling date across the tubes to prevent burn-in.

Its acrylic case is pretty swank-looking too, making us think its $400 cost is probably just about right.
