Lume on the Celsius 9

The lume on this watch (at least for me) is perfectly adequate, mine lasts for a couple of hours too, for example i went to bed in a tent on Hadrian's wall at 10, when it was dark, and woke up at 4 am (still pitch black) and the watch was perfectly legible after that period of time, and if the lume is no longer readable, you have the decently bright backlight on the digital display. (Note the lume looks lesser in the second picture because my camera had a hard time focusing on the digital display as well as the lume, they were taken seconds apart and the lume was the same)
