Moon Ascending Descending Slope.
All the calculation is done locally in pebble ( no link to internet is needed). The moon declination slope will shown as a real calculated graph in pebble by pressing the center button. The ticks on the time axis are in units of day. The ticks on the declination axis are in units of degree. The down button on the right side of the pebble watch will show the position of the moon in celestial coordinates (RA,DEC). If the current declination does increase (ascending moon) we call it in Swiss German (obsigänd) if it is in the descending it is called (nidsigänd), the descending moon. The numerical value on the right is the first derivative of the declination to the time (degree/day). The value d is the second derivative of the declination to the time (degree/(day*day)). To get suns position (RA,DEC) click the upper bottom on the right of the pebbel. The difference of the RA values are representative for the moon phase, as example 12 hour full moon, 0 hour new moon. 
A drawing of the moon phase, according the difference of the right ascension (RA) of the moon and the sun, will be included in the first picture together with the moon slope ascending descending curve.
Remark: In a next release and if needed the accuracy of the object positions could be improved, now in the order of a few minutes, to less than one minute.
