Time runs slow
Mission One is based on smart-wearable device structure which requires internet signal to calibrate time.
So it will slowly run late if disconnected with a smartphone. (Most smart devices without internet are the same)
If MISSION ONE is connected with ATMOS APP. It’ll calibrate the time background.
※ We have improved it from the firmware 1.019. Please update you MISSION ONE to the latest: Update firmware
