It would be really nice to have a possibility to setup two watchfaces by time.
e.g. one for timeframe 1 and one for timeframe 2
I’ve one watchface for the night and one for the day, would make life much easier. 
Thank you
While we’re at it, watch faces set by:
- sunrise/sunset
- detected sleep status
- Detected workout/heartrate status
Essentially, a hook on events or states that allows to associate a watch face with said state or event
I think this would be extremely useful.
I was going to ask for this! Also maybe watch face scheduling by day and time - I tend to use a different watch face at work than I do at night and in downtime and holidays.
