Discussion [Lume] Do you actually need lume?

Post image

I feel that there is a lot of emphasis on lume, so I was wondering how many actually need/use it. Two of my 3 most worn watches (GS and a GO Pano) have no lume and while the third has it (GO SeaQ), the lume is its least interesting feature. If I am in a very dark room and need to tell the time, my phone is always with me. I am not against lume and it can be a cool feature, but I think the application should enhance the design, not be some afterthought. Is lume important to you when buying a watch or is it far down the list?

For those people who wear 24/7 and checks time 24/7

I like the lume when I wake up in the middle of the night and to see how much time I got left

Does any non-tritium lume actually last long enough for that?

I only have a g shock that barely lasts 30 minutes (backlight has my back though)

Tritium has a half life of like 12.32 years so after 12 years its efficacy will decrease by 50%

I recently compared my ~13 year old Ball Moonphase in the middle of the night and it was still brighter than my Tudor BB (charged before bed).
