Wryst Variance concept lets you play around with the looks of the watch. And by looks we don’t just mean the strap, although the Wryst will work with different straps, keychains, and even dog tags. What is unique about the concept watch is that it can have its face change color and design as well. The face of the watch works as a display that can change into various different styles, and clearly is the USP of this product. Wryst Variance concept has been designed by Ben Pritz.
