Using smooth seconds in any kind of math for rotation, position, opacity, etc. results in a choppy/unsmooth version on the watch, even though it appears correctly in the WatchMaker app.
Found a kind of bug on tag {drs} for seconds. If used tag {drss} problem doesn't happens on Moto 360. The problem is that when screen awakes seconds do like this:
2... (a time for 1s)... 3... 4... 5... 6... 7 and back to 6 before turn of screen.
