Abstract: Watch bands described herein include electrochromic features that provide adjustable color control based on an applied voltage to offer a variety of colors and color combinations to be displayed by a single band. The user or a control system can control, select, and/or adjust one or more colors of the watch band for visual display. Accordingly, a variety of colors can be displayed at different times without requiring different watch bands for each color or color combination. The color changing features can be used as a visual output of information from the watch to the user.
