While waiting for Garmin to fix the brightness problem of the Epix (way too bright in the dark) I'm trying a watchface with dark colors (gray instead of white text for example), which is still bright enough most of the time.

I personally set my watch to the dimmest brightness setting, but if you find it too dim during the day you can increase the setting. At least we have a way other than too bright, brighter and way too bright :-)
