- Duration means approximate time until power runs out and the watch stops at the level indicated.
- When the power reserve level is "0", the watch cannot register smartphones, cannot be connected with them and cannot remove registration information.
- Pressing button A does not change indication of the function hand when the power reserve level is "0".
- Connection is disconnected when the power reserve level becomes "0". However, basic functions of the watch are still available.
- Some basic functions become unavailable as the second hand starts to move once every two seconds (insufficient charge warning function).
