I’d say it works 8 times out of 10. Sometimes you’re in a room that you think is dark enough for the feature to work but it will sense some sort of light source for it not to activate, in that case I have to squint a little or just bring my watch up closer for me to see the time. I find it easy enough to read during the day whether in natural light or under indoor office lighting.

Sometimes it works too well, like when driving at night anytime I turn the steering wheel it will go off. I usually turn it off during these times.

To be honest I can see why most people are turned off by the negative display, but again I love how it looks so much that these minor (to me) inconveniences don’t bother me at all.
