I quite enjoy the analog watch faces. Everyone’s sartorial tastes are different but I think some of the faces make the Apple Watch look like a respectable timepiece.
The one complication I like to keep on visible if possible is WaterMinder. I’m susceptible to kidney stones (only had one so far!) so being sure I have had enough to drink every day is the best way to prevent them.

And watchOS 10 really helps to keep handy info top of mind. I keep battery, WaterMinder and activity rings up top, then weather then calendar events.
