Smartwatch - Black Used 1-2 times, but not suitable for "oshi-katsu" (supporting my favorite idol/character), so I've been storing it. I used it with a protective film, so it's incredibly clean. I will include the protective film as it is. Features: Heart rate monitoring, sports modes, blood oxygen saturation, blood pressure measurement, sleep data, music control, weather, alarm, breathing exercises, messages, voice assistant, SOS call, games, toolbox, menstrual cycle tracking. You can use it by downloading the dedicated app and linking it to your smartphone. The instruction manual is in Japanese, so it's easy to understand. The watch face is customizable. Recommended for those who want to try a smartwatch. I will ship it in simple packaging to keep the price low.
