This Atomic Clock Wristwatch Only Loses A Second Every Thousand Years

If you pride yourself on not only being the person who always arrives on time, but also the person with the most accurate time, then Bathys Hawaii’s got one heck of a watch for you. This monstrous creation, now just a prototype, is an actual atomic clock you can strap to your wrist that guarantees accurate time for at least a millennium.

Appropriately called the Cesium 133, the watch is powered by a $US1500 chip called the SA.45s CSAC (short for chip scale atomic clock) that contains everything you need to keep perfect atomic time, including caesium gas, a laser and a photodiode detector. You’ll have to take their word for the incredibly precision though; while the Cesium 33 can keep track of each tick down to the microsecond, the folks at Bathys Hawaii have still opted for a traditional analogue watch face.

While it looks — and is — chunky above, this isn’t just a concept. Bathys Hawaii is actually working to perfect and refine the Cesium 133 for a 2014 release. The final version will supposedly have a much smaller carbon fibre case, plus a series of LED status lights for monitoring the power reserves on its built-in rechargeable lithium ion battery. It will also come with a price tag of around $US12000, and while expensive, this is a rare opportunity to pay for functionality and totally get your money’s worth. [A Blog To Watch via TechCrunch]
