When I first saw the Ring Clock I thought it was another rendering or prototype. I was sorta right. You can buy the Ring Clock ($185) on indiegogo if they hit their funding goal.
The ring clock tells time using military standard for the hours on top and minutes/seconds below. To turn on the LEDs (either blue or orange color) you simply spin the face. The Ring Clock battery will last for about one week before needing to sit on the included wireless charging dock. It is made of surgical-grade stainless steel and is water-resistant.
