  1. Connect the watch’s charging cable to a power adapter or a computer’s USB port.
  2. Put the watch into the charging base. Pay attention to the direction and position of the watch, and make sure that the metal contacts on the back of the watch fit closely with the charging base.
  3. When charging starts, the watch screen displays the charging progress.


  1. Please use the charging base that comes with the watch. Make sure that the charging base is dry before charging.
  2. Please use a 1A or above power adapter.

Wearing the Watch

  1. Wear the watch strap neither too tight nor too loose, and leave enough space for the skin to breathe. This makes you feel comfortable and allows the sensor to function.
  2. When measuring blood oxygen saturation, wear the watch correctly. Avoid wearing the watch on the wrist joint, keep your arm flat, maintain a comfortable (appropriately tight) fitting between the watch and the skin of your wrist, and keep your arm still throughout the measurement process. When affected by external factors (arm sag, arms sway, arm hair, tattoo, etc.), the measurement result may be inaccurate or the measurement may fail and provide no output.
  3. We recommend that you tighten the watch strap during the workout and loosen it afterward.
