Atoms

The Cesium 133 from Bathys Hawaii is the world's first true atomic wristwatch. Boasting an internal cesium atomic clock that's claimed to be accurate to one second over 1,000 years, the Cesium 133 is a rather expensive but utterly unique timepiece.

With all the fuss over the recent influx of smartwatches, you'd think that a new wristwatch that simply displays the time on an analog face wouldn't cause much of a stir. However, when that watch is claimed to be "the world's most accurate wristwatch," people perk up and take notice.

The Chip Scale Atomic Clock is a matchbox-sized atomic clock, that uses one one-hundredth the power of its conventional counterparts.
