Central Standard Timing has developed the CST-01, the world's thinnest watch with an E-Ink display, and the accessory is currently on Kickstarter to raise funds.

At 0.80 millimeters (0.3 inches), the CST-01 is even thinner than a credit card. Moreover, the accessory is also extremely light, weighing only 12 grams (0.42 ounces).

"The CST-01 weighs less than 5 pennies at 12 grams. Because of the comfort, weight, and thinness, if we didn't want to keep looking at it, we would forget we were wearing it," reads the description on Kickstarter. "Everything about the design and engineering was thoroughly considered for its functional and aesthetic benefits. The CST-01 is the most minimal expression of a timepiece, it's 'time' embedded in a band."

According to Central Standard Timing, it made the CST-01 by laminating thin, flexible components into a 0.5mm pocket embedded into a single piece of flexible stainless steel. Traditional digital watches generally use the same chassis found with analog watches, but CST-01 aims to change the game.

To keep the accessory as thin and light as possible, the company decided to eliminate any knobs or buttons on the watch itself. Instead, users can charge the device and set the time on the included base station. As a result, the watch itself remains light, thin, and clean, sporting only an E-Ink display that shows the time.

The CST-01 also uses an embedded Thinergy Micro-Energy Cell (MEC), which, according to the Kickstarter description, allows for 10,000 charges and lasts for over 15 years. The watch can charge in as little as 10 minutes thanks to this technology and it should last for a month on a single charge. The company plans to assemble all CST-01 watches in the U.S.

The CST-01 is currently running a funding campaign on popular crowdsourcing site Kickstarter. The project will only kick off if it reaches its $200,000 goal, but at the time of writing it has already raised $176,640. The campaign runs through Friday, Feb. 22.

Pre-orders start at $129, which will get supporters a CST-01 in the color of their choice (white or black), as well as the base station. Estimated delivery is in September 2013, with free shipping in the U.S. and a $15 fee for international shipping.
