LAS VEGAS--The fight to build the thinnest watch has finally been won, folks. At least for now. Central Standard Timing has partnered with E Ink to create the CST-01; purportedly the world's thinnest watch.

At 0.80mm the watch is thinner than a credit card. I briefly got a chance to hold the extremely light watch and it is indeed the thinnest I've ever seen.

According to Central Standard Timing, the patent-pending CST-01 is assembled by laminating thin, flexible components into a 0.5mm pocket etched into a single piece of flexible stainless steel. This is different from traditional digital watches, which typically use the same chassis used for analog watches.

The CST-01 also uses an embedded Thinergy Micro-Energy Cell that charges in 10 minutes from an external dock and has a lifetime of 15 years. All CST-01 watches are planned to be assembled in the USA.

The CST-01 is available on Kickstarter. Preorders start at $129 and the device is expected to ship in the second quarter of this year.
