Nixie tube watch based on STC51 microcontroller

Introduction: 2 Niwa tubes. When you raise your wrist, the hours will be displayed first, and then the minutes will be displayed. The Niwa tubes consume a lot of power, so the NIWA watch cannot stay on. It has a built-in gyroscope sensor, so you can only see the time by raising your wrist. The watch will light up when the time is up, which is the same as current smart watches.
