The designer says ”Inspired by scanning devices for scanning targets in sci-fi movies, the Sonar Watch has three themes – blue for sonar, green for radar, and red for a scanner interface. The time is shown as three targets which are lit up. By pressing a button, a radar/sonar/scanner animation will play. The dots represent the hour, minutes and seconds. Cool, novel design. Definitely something I could see Tokyoflash selling”.
