Earlier this year, Bathys successfully wrapped up a crowdfunding campaign on Kickstarter to raise funds for a limited run of atomic watches that would be able to tell time with an accuracy like never before. Bathys describes that its watch "Uses a chip-scale atomic clock (CSAC) to precisely divide a second into exactly 9,192,631,770 vibrations of the cesium 133 atom." As such, the watch was appropriately named the Cesium 133.
The prototype watches were built with carbon fiber cases, which helps to cut down on a lot of the weight that is traditionally found in a wristwatch. The watch has a large rectangular plate and a small round cutout for the watch face, but the design pales in comparison to the impressive timekeeping features of the atomic watch.
