Almost non-customizable (for the moment) watchface with data that I'd like to have presented on my Instinct's watchface. -Hour in military format -Zulu/UTC time -Date in format DD.MM + weekday -DECENT HR plot (up to 6hrs - this range is customizable via menu) -Stress indicated by thickening x axis of HR plot -Current HR, Max/Min HR within the range chosen -Battery in % and days -Sunrise and sunset hour -Day progress bar with day/night + hours marked -Sun/Moon current azimuth and altitude -Sun/Moon azimuth cardinal direction -Day/Night progress percentage (above Sun altitude) -Moon phase icon and percentage (above Moon altitude) -Steps -Alarms active (indicated by star at top left part above HR chart) When seconds inactive, there's jet icon with indications: -Fuel tanks appear when device is solar charging at maximum rate -Emission rays appear when watch is connected to the phone The watch calculates positions for the next hour every full hour, then every minute update the watchface with current data. You can turn debug mode on to see when (L)arge update happens (full calculation of all the coefficients), and then when (S)mall update happens (using precalculated data to update current view).
