The stylish CST-01 super-thin wristwatch has no buttons and has only one function... to let its wearer know what time it is
An exploded view of the CST-01 e-ink wristwatch
Chicago-based Central Standard Timing has designed a wristwatch featuring an e-ink display and built-in battery that's just 0.8mm thin
The CST-01 has gold-plated contacts on the watch that connect with pogo-pins on the charger to top up the built-in Thinergy Micro-Energy Cell
The CST-01 is held in place on the charger using magnets
The CST-01 comes with a white-on-black/black-on-white display (with a custom font) that's readable in sunlight with a 180 degree viewing angle
A single piece of flexible stainless steel has a 0.5 mm channel etched into its upper surface, into which the flexible e-ink components, a Seiko Epson SoC and an embedded Thinergy MEC are laminated
The lack of a back-light does mean that you won't be able to see the display in total darkness, but a little ambient light should make the face visible
Central Standard Timing has included a pledge level on Kickstarter where backers can receive one white-on-black CST-01, one black-on-white version and a charge dock

Article Summary
Though e-ink watches have been around for a few years now, most, like the Touch Time, tend to follow the same form factor as their LCD-screened cousins, which are themselves based on analog ancestors. The patent-pending CST-01 from Chicago-based Central Standard Timing is a different proposition altogether. Claimed to be the world's thinnest watch at just 0.8 mm thin, yet still managing to squeeze in a rechargeable battery, it makes use of segmented (rather than pixel-based) e-ink technology, has no buttons or knobs and has only one function ... to let its wearer know what time it is.
