Watch Performance and Specifications

Q2: Why are their gaps in the altitude and barometric pressure graphs, and why aren't displayed number of step and calories burned values correct?
A2: Altitude, barometric pressure, number of steps, and other readings are not recorded while the watch is turned off or while it is in the Multi Timepiece Mode. Because of this, no data is shown in graphs or incorporated into displayed values during such periods.
Also, lack of connection between the watch and phone for a long period will also cause gaps in graphs and incorrect measurement values.
