CASCHO: Bluetooth calls and AI voice assistant
For the busy professional who wants to stay connected without being glued to a phone, this smart watch is a practical companion. The built-in speaker and microphone let you take calls by raising your wrist, so you can keep moving during your commute or workout. The AI voice assistant works with Siri to check weather, set timers, or control music—all hands-free.
Health tracking goes beyond step counting. The optical sensor monitors heart rate and sleep stages, breaking down deep and light sleep. Women can track menstrual cycles right on the watch. With 120+ sports modes, it records steps, distance, and calories for running, cycling, yoga, and more. The 1.85-inch HD display stays readable in sunlight, and you can customize the watch face with your own photos. Battery lasts up to 7 days of heavy use, so you won't need to charge every night.
