You've posted this in the top level of the general showcase forum and, with such a generic title, it may not be noticed by anyone with knowledge on your specific watchface in question. i would suggest you post it in the thread related to the specific watchface (which I think is actually showing just a few down from here - "WATCH FACE: SHN Tactical".
The fenix3 doesn't have the display hardware needed to display seconds all the time, so on that device, seconds can only show for about 10 seconds after a wrist gesture. The first devices with the proper HW for seconds all the time are the fr935 and fenix5 series.
