Like the Geak Watch 2, perhaps the next version of the Tago arc could utilize a dual screen design. By overlaying a colour OLED screen on top of an e-ink display, the bracelet could be lit up in glorious full colour but then switched to e-ink when the battery is low (this approach was also utilized to great effect by the creators of the Yota Phone 2).
Unfortunately the early bird special is sold out, as has the Valentine's Day special. The Tago arc can, however, be pre-ordered for $259 (£168). Estimated shipping date is December 2015, and international shipping will be offered for an additional $15 (£10).
The company recently announced a stretch goal perk. If the stretch goal is met, the Tago arc will be available in several colourful silicone cases, that fit onto the bracelet concealing its original frame.
