CST-01 Watch
"The World's Thinnest Watch" is a bold claim to make — but at just 0.8mm thick, we're inclined to believe it. The CST-01 Watch ($130) achieves this by packing its guts — a battery, E Ink display, and controller chip — into a 0.5mm pocket etched into the single-piece stainless steel band. That doesn't leave much room for controls, of course, which is why they're mounted on the recharging base — although with a 10 minute charge time and month-long battery life, you're not going to be visiting the base very often. Available in white or black.
