i got a light blue one from the initial run and at first i loved it and used it everyday but as time went on my wrist felt more and more like it needed to be naked & the Durr felt more and more distracting... so i stopped using it... however i still have it sitting next to my bed waiting for the day when my wrist becomes less claustrophobic. Overall im glad i bought it because it was an interesting thing to try out... if you ever want to make another interesting product, i would look into what bodyhackers and transhumanist people are doing. a lot of their inside-the-body devices (magnets inserted under finger, gps chip under the skin) could work equally well as outside-the-body accessories (a magnet that clips to your finger, or a gps chip in a bracelet). maybe im wrong. i dunno. but i think its worth a shot.

Are you planning on making an app for the Apple Watch? I really think you should (by taking advantage of the topic engine) as the $100+ price point for the physical DURR watch was inaccessible to most people. An app sold at $0.99 would make several times as much as it would be an impulse buy.
