Mine is also too dim when the brightness setting on watch settings is on low.. when it is on medium sometimes its too dimmed sometimes is ok.. try setting it to mid or highest brightness setting and see if it helps. I also have another problem when the brightness setting is on low: it has a gradient overlay, the screen is not evenly lit! Top and bottom parts of the screen are darker then the middle! Has anybody else experienced this? My model is Watch Ultra that is a month old and I haven’t noticed that until yesterday. Tried unpairing and repairing but didn’t help.
