Wrist to Airwaves — The Casio TM-100, the Watch That Turned You Into a Radio Released in 1987, the Casio TM-100 wasn’t just a digital watch — it hid a tiny FM transmitter, antenna and microphone that let you broadcast your voice to nearby radios. This one-minute video shows how the TM-100 worked, why it flopped commercially yet became a cult collector’s item, and what it tells us about 1980s design daring and tech experimentation. #Casio #TM100 #RetroTech #VintageGadgets #techhistory
