The product is a three piece system which allows the user to switch between a strap version and a clip on version if they like. The original concept was to use metallic finishes and matte PU to create a product with high perceived value and relate to larger trends in the technology industry. Unfortunately, as the project grew in scope, the "fashion technology" aspect was dropped in favor of a more "mass" approach. This resulted in the metallic finishes being dropped in favor of a satin black finish to the head unit and then colored straps.
The construction also evolved over the course of the project, with the two separate straps being bridged by a piece of stamped metal. The barrels where the head unit slides into the strap or clip were tapered so it could only be slid in in one direction. The display has evolved from the original idea of an OLED to a small RGB display but the touch screen was kept (this is actually not a full touch screen, it is simply a touch plate located under the lens and running to the left of the display.)
