Hallo Greg, All my Casio's, like the Lineage line, have useful lume. The backlight functionality on all of these is more than sufficient. Only the oldest and cheapest models have poor backlight. On the other hand, even that is enough in pitch black at night. Never had any problems on the subject with Casio's. Thanks!
the lume is one point, why casios, as much i adore them, cant be one of my daily watches. im realy a sucker for good lume. and you realy dont need to spend a lot of money, for a great lumed watch. one of the best lume of all watches (including Rolex) is the Citizen BN150, for round about 200€. you can charge it up befor sleeping and if you wake up 8 hours later, you can still see the lume. All Citizens i had so far, had great lume, regardless of the price. also Orient and Seiko have great lume for a fair price (better initial glow then Citizen, but fades out a bit faster, but keep a visible glow for a long time). for the digital displays, the electroluminesence of the most Casios is great.
@@shaswatmulmi127 modern lumes don't are radioactive anymore. they use mostly strontium aluminate as an activator, not longer tritium or radium, therefor its not dangerous. Casio probably uses some veriety of Superluminova like almost the whole watchindustry. If you are interested on the chemistry of nightglow, you should probably watch the video "Making glow towys from scratch" from the phantastic chemistry youtuber Nilered. He breaks down all chemical steps and substances for lume in a realy entertaining way ;)
I don’t think about the lume much on a daily basis, but I don’t do much in the dark anyway. Maybe if I could go to the movies.. but I try not to watch the time during a movie... and maybe the movie business is dead now anyway.
I have no issues checking the time with the lume on my Casio at 5 AM (i do not need the light button). Tritium illumination from other watches is definitely brighter but they charge more money for it.
Tritium is still available on some watch dials, the material is nowadays contained in tiny glass tubes of various shapes and sizes, which are then mounted on index markers and hands of watches, so the material is no danger to humans anymore.
The radiation level of tritium tubes is about the same as a banana. Of course you do not wear a banana on your wrist all day every day unless you are very strange.
I have an AWGM100B, among many others. But, on the 100B the fact that only the tips of the hands have lume was a bit of a shock at first. Thankfully the LED works well at night for reading the hands.
is it normal for the lume to deplete on my casio mdv-107? i have the pepsi blue version and i thought my watch doesn't have a lume feature ever since I bought it I can't see anything in the dark so I found out you need to charge in order to have the lume glow but eventually it depletes after minutes?
Great video, the Lume on Casio is mediocre, generally But with some luxury watches lume purchase from ebay and a precise syring, it's possible to relume all Casio watches to a level of 10000 usd Grand Seiko! I relume my analoge watches in this way, pay about 30 dollar for a complete kit, that relume about 20 watches perfectly.
From what I remember of some physics classes I school, light is an electromagnetic wave and thus can't be "stored". Instead, light waves hitting other matter can bring atoms / electrons of some matter to a higher energy level, and by falling back to a lower energy level, that energy will be released, and can result in heat, light, or other radiation being emitted.
Yes, the physics of what’s really happening is not quite the same as what I said here. It kind of looks like you “charge” the lume, like charging a battery, and then the “power” of the light slowly drains out. And if you understand how to use a battery that you can charge then this is somewhat analogous. But these aren’t batteries.
Hi, Greg, I have my new g-shock GW-M500A-1CR. My question is the receiving indicator stay on in the screen for a long time I set my watch following your videos and the users guide book. It's normal that the antenna stay on all the time, can you help me and explain to me, thanks.
The radio icon (which looks like a satellite dish) will blink while the watch is trying to receive atomic time data. If the reception is not successful then the icon will not be visible. If reception is successful then the icon will stay visible. If you see the icon all of the time then your watch is consistently setting itself to the right time.
I don’t know what they use for the lume material but lume on Casio watches is never very impressive. I seriously doubt they use anything radioactive in these Edifice watches.
I think my Casio Gshocks are ok for lume. But they have great backlighting and so it's not a huge deal. For me lume on the hands is enough. I don't do deep sea diving.
If I can read the watch in the dark when I wake up at 5AM with dark-adjusted eyes, I consider the lume to be adequate.
The only Casio I have with decent lume is my Oceanus.

Thank you ,i was wondering why my Casio Baby G stopped glowing in the dark ,very informative video 😊

So a Ball watch would be your thing. Little microtubes of tritium coated in phosphor. 🙂
I have Casio Edifice EFA-119D-1A4
And it has a lume ,is it radioactive?what is that material in that lume

Thanks a lot for reply.😄
The Lume on my Ga-2100 (Casioak) is pretty poor but at least there’s a backlight
I'm specifically looking for an analog glow watch with an illuminated second hand or completely hands-free back lit.
Nice and interesting, awesome collection Greg, on your daily basis, do you find the lume necessary?

@@GoodTimekeeper lmao 😂 a dead business, you’re cold as ice 🧊

160b bucks for aragon with tritium
How long will it last once exposed to UV lights?
Lume is only important if there's no backlight. Though having both can look quite fancy sometimes.
Tritium is still available on some watch dials, the material is nowadays contained in tiny glass tubes of various shapes and sizes, which are then mounted on index markers and hands of watches, so the material is no danger to humans anymore.

And it has a lume, is it radio active . What material is used to make it glow. Your answer can be helpful to me😊

Also blue lume > green
I really like you voice and nice video!
GW3000 and GAS100 lasts all night which is great when you want to preserve your night vision. GW3000 has no light so it has to have good lume BTW.
I wonder if the GAW100 is similar to the GAS100 in that regard. (Hint: I will soon know a lot more about the GAW100.)
If you want some flash for orange fire models, there are orange silicone nato straps.
is it normal for the lume to deplete on my casio mdv-107? i have the pepsi blue version and i thought my watch doesn't have a lume feature ever since I bought it I can't see anything in the dark so I found out you need to charge in order to have the lume glow but eventually it depletes after minutes?
What is funny that i only care for lume and i never had to use it lol
Any Casio lasts around 8 hours glowing . Any or do i need to look at a different brand that actually has a lume that work.. not the backlight

Wow. That sounds like fun... but I don’t know if my fingers are steady enough to do it.
@@GoodTimekeeper it's fun and simple, you can even built a simple training set-up for mastering reluming.
Would be interesting to see this....
Lume orange not bad i like it is possible for casio many colors ? Nice video greg thanks you for you jobs !!🙏👍🇨🇵

Ball Watches have microtubes of Tritium coated in phosphor. Amazing really.
Have you compared them to Seiko lume?
