I’m really curious about the point of lume, besides the obvious. What I mean is that through casual wear it may charge but also goes dark again within 3minutes of being in the dark. Any profession that required lume hands almost certainly switched to digital/wrist computers, but what was the original process? If I know I’m going to be saturation diving in the afternoon, do I have to put my watch under some lamp all day. It’s just all a bit silly compared to something like tritium tubes with an actual constant glow.
![[SeikoSRPD59] Not sure why other watchmakers don't look at Seiko, and think "we need good lume like them!" Am I crazy?](https://alien.top/pictrs/image/4d179537-281f-469f-82f0-909d0f739df0.webp){kind=link}

Good lume can last a long time. I usually go to sleep at 11 pm and the lume in my wristwatch is still glowing by the time I wake up at 5:30.
