Looksee's Eyecatcher Bracelet is a smart wearable device that has a large curved E Ink display (150 PPI) that can show custom images and phone notifications. The display is always on, and the device should last for months on a single charge (it does not show time) - depending on the number of times you will change the display. If you update once every hour it will last for a year.

LookSee launched a successful crowdfunding campaign to fund the Eyecatcher, which costs $400.
