The world's first atomic watch

atomic1.jpg

A stickler for accuracy? A grammar Nazi with a tendency to jump down the throat of anyone who misquotes Hamlet? We've found your perfect watch.

This is the Cesium 133, an atomic clock watch from little-known Hawaiian manufacturer Bathys. This isn't like that 'atomic watch' your sleazy uncle used to have that synchronized with an atomic clock via radio waves. Oh no. Bathys Hawaii have managed to squeeze a chip-scale atomic clock into a portable, wrist-worthy housing. Why is this cool? Because it can "precisely divide a second into exactly 9,192,631,770 vibrations of the cesium 133 atom - the scientific definition of a second by the International System of Units".

Sure, your £6 Casio will still tell you when it's time to go home, but the Cesium 133 is a moment in watch manufacturing history - a union of mechanical motion with atomic accuracy. The technology in this little box of tricks will be accurate to 1 second in 1,000 years time (so long as the lithium battery is recharged), making it the most accurate watch ever made.

Currently looking for funding on KickStarter, £3,500 will get you your very own Cesium 133 - though as many of us have no real need for an atomic watch, there are more affordable, less accurate timepieces available as funding perks. Head over to the project page to find out more.
