The world's thinnest watch CST-01

Central Standard Timing is showing off what it's calling the "world's thinnest watch" at CES 2013: an E Ink watch that's a single, razor-thin cuff.

The watch is 0.80 millimeters thin, and the company says that it was able to create it by laminating flexible components together into a single piece of flexible stainless steel.

In the world of mechanical watches, anything under about 8mm thick can be called an ultra-thin, with the thinnest watches coming in around 4mm thick. But the CST-01 comes in at 0.8mm - that's not a typo, 0.8mm. Starting with a thin piece of stainless steel, Central Standard Timing etches out space for the e-ink display, micro-engergy cell, and Seiko Epson controller. It's an amazing example of an object that contains nothing, and I mean nothing, superfluous.

The CST-01 is assembled by laminating thin, flexible components into a 0.5mm pocket etched into a single piece of flexible stainless steel. In order to make the watch as thin and minimal as possible, there are no buttons or knobs on the watch itself. Charging and setting the time is done on the included base station, and for those outside the US who prefer a 24 hour time format, this is also user selectable from the base station.

Unsurprisingly, the $200,000 goal was surpassed extremely quickly. At time of publication, the campaign has raised $436,813 from over 3,200 backers, and there are still 37 days to go.
