Lange's luminous features tend to dim quickly. I am curious how long the luminous charge lasts on the ZW Phantom during typical use, when the wearer does not deliberately charge it up by putting it near a bright light. Is the time readable a few hours after it gets dark? If you were seeing a 2-hour movie, could you read the time throughout? I did try that experiment on the Grand L1 MP version but don't remember the result. I will have to try that again.
