The magnetic hinge system easily connects to the frame to make changing colors quick and easy. Colors come in matte, metallic, clear colors, glow in the dark and more. For $25, a backer gets one rim and four side colors of their choice. Expected delivery is June 2014. And if you like this idea, you might also want to check out the Mod-to-Order watches campaign.
