Understanding Tritium : Everything You Need to Know, And a Few You Don't (Science Time) 

"The power of the sun in the palm of my hands." -Some guy who has 4 mechanical arms who wants a lot of tritium for his machine

Not boring at all. Very interesting info. Keep up the good work.

Well done. You clarified some points that I didn't understand. Kudos to you!

This is a much needed video! The production value is great, as usual. Keep it up!

I truly appreciate you taking the time to explain this to us non scientists! Much obliged!

I was recently introduced to radioactive materials in science class, thank you for explaining a lot about the energy and how to work with them! Keep it up man!

I love knowing what's the science behind something before making any choice/purchase. Your video was very clear and relevant to me. Thanks a lot!

I’m glad I found your video on this. I’ve been watching your channel for years but for some reason didn’t watch this one before and I appreciate your scientific background and explanation.

Great explanation. Nothing new for me personally here, but - title says it all - it is indeed everything you need to know. Took me a while to dig it all out elsewhere, from multiple sources. I would be much better off just by watching this one first. Thank you also for the impartial advice and for allowing us to make our own decisions. Really appreciate it.

Learning about the technologies our beloved timepieces are built upon is never boring. Very good presentation and editing too. Maybe this could be the beginning of a series? How about telling us about what jewels in watches do, and their history. Or one about what controls the accuracy in mechanical and quartz watches, and why one is more accurate than the other. Maybe one about the forgotten predecessors of quartz: tuning fork (eg. the Bulova Accutron, which I personally find very interesting. The Omega is not the only moon watch) and electromechanical (eg. the Citizen Cosmotron)? Anyway, your work is appreciated :)

Great great explanation. Even 3-4 years after you posted it, I am very happy I found your video. Thanks much :)

Fantastic video. You really went into great depth without becoming overwhelmed or boring.

Your video is now 2 years old but still teaching us newbies everything we need to know about tritium Shane. I bought an obscure watch from Times International at the start of my obsession called "CPLA General Watch"! It has tritium tubes on the hands and indices (T25 I suspect). There is no "half life" with your perfect explanation to us laymen. So glad this video of yours is still available. Incidentally, I've just turned 65 so a half life of twelve and a half years should do me nicely😄

Thank you so much for taking the time to create this educational content; quite fascinating and informative! Keep up the great work 🙌🏼

I love the way how You explain things... So calming, and straight to the point. Good work Sir

Excellent video. Very informative, clear and to the point. Without the straight to DVD theatrics nor BS of other channels.

You explained pretty much every tritium related question I had, thank you very much:)

Excellent video. Thanks! Your soothing voice, stunning photography and gentle manner are all exceptionally easy to watch/listen to. I have a Carnival tritium watch and even though it's 'only' 25 it is plenty bright when my eyes are adjusted to the dark. Moar tritium!

Clear, concise and to the point. Excellent video.

Wonderfully interesting and well spoken video, a pleasure to listen to. Explained all I needed to know and then some even though I am looking at tritium for a keychain and not a watch. Also awesome voice, you should consider doing ebooks or readings.

Excellent narration of a subject little known. Thanks for taking the time to explain it to the watch collector's community.

This is one of most informative video I watched in you tube. Thanks. I enjoyed it.

Excellent presentation! Thorough and very well structured informative video!

Thank you! this is the BEST video I watched about tritium! So good, that no other video about tritium is needed, thank you for your work!

I'm all over the place with youtube videos. really I watch a bit of everything and I just wanted to say. your description and way of education for some reason, is among the best I've ever seen in my 10 years on this platform.

Great knowledge. A must watch for even the casual collector. Thanks for posting.

That was a great video. Thank you for this! I only found out about these watches an hour ago so the information was really needed. Thank you again!

Informative and very well done. Everything you need, nothing that you don't. I like your style.

Boring but not boring. Informative. Exactly what I was looking for.

This was a great video. Well explained and presented. Thank you for you time and video.

Wow. Amongst so many useless "reviews" and product demos did I find this very informative, concise and just put video. Well done, thanks. No I know what's up with this whole shebang around tritium tubes.

Hello Shane, Sweden here again. This was not at all a boring video, I found it rather interesting. It so happen to be that I am a bit of a science freak, physichs, chemistry, astronomy and you name it. When I am scrapping in the garage I usually have the pad going with a lecture on something, Laurence Crauss, Brian Green or Neil Degrass Tyson, Ed Copeland.

Excellent video. Even as someone already with tritium, (a byproduct of my chosen profession) I found it very interesting, especially when you got into how tritium works together with a phosphor to generate light. The thumb rule I remember is that after five half lives, a radioisotope is considered pretty much decayed off. BTW, somehow I am not surprised that you have a science related background. (yes, that's a compliment ) Oh yes, More "How it works" segments would be good.

Super informative, thanks for making this.

enjoyed the video and learned a few things - thank you! I first used tritium watches for night time maritime work on pilot boats.

Great informative video! Thanks, I have an vintage Tag heuer with tritium that no longer works under normal lighting conditions....

Shane, This video had the perfect amount of info for a non-chemist to follow. It was interesting and informative. I think there was one small mistake, though. Around the 6:46 mark, I believe you meant to say "which is less dramatic than it sounds", or "which sounds more dramatic than it actually is". Still a great video. Thank you.

Thankyou that was really interesting . You really spelt it all out and answered everything I was wondering about.

Thank you for explaining something no one else ever has,,iv used Tritium most of my life in various applications and never could explain it to anyone before other than to say its radio active.

An absolutely fantastic video. Very informative. Thanks for sharing

Nice job! Learned a lot from your video. Nice to know not all tritium are created equally.

You're a very good teacher, put it simple and easy to understand

Very informative, really enjoyed this one!

Thank you. I’ve been worried about the safety of the tritium tubes in my watch. Knowing they are safe and coming from a chemist means a lot.

Wooow!! Good topic! I didn't know there is a quality of tritium like different between: 25, 100 :) that was new for me :) Radium is oldschool... I remember some books about WW2 and authors wrote about own watches :) This video is very helpful :)

Very informative video, I can see it's incredibly useful for those less scientifically adept given the layman's terms description of the processes going on. I am an element collector but I have two tritium tubes sent as a gift! Now I see them in a different light! (pun intended!)

Just became a subscriber. Excellent presentation. Interested to see your other videos.

Awesome info too. Can't see myself investing in a Tritium watch for exactly the reasons you specified. Was wondering though, does traditional lume lose brightness over time as well?

Given all the scare mongering and drama in the news and the internet..... its always satisfying to see an expert, calmly sit down and deliver FACTS. Well played sir.

Really well done with lots of useful information. Thanks!!

Very good explanation of tritium. I have a t100 quartz watch and use it often, especially when I go to bed. If I wake anytime during the night it's still glowing nice and bright. I know they have a 25 year lifespan but then again at my age so do I.

So well explained, answered every question. Thank you 👍

I was thinking of buying a tritium watch t100 that's around 12yrs old and wondered if it is worth it, this tells me for the right price it should be fine, so thanks for educating me with your dulcit tones ☺️👍

thank you so very much. this was invaluable info. im currently looking for some "nite sites" and just needed some tritium education, and this was very very informative. thank you.

Very well done and informative video 👍👍 Thank You!

Superb! Your content sir is one of the few gold nuggets pyrite mine!

Superbly explained. Thank you.

This is a really well done video. Thank you

So awesome man! Very useful and entertaining!

Used them on AK sights Yugoslavia. Other countries used clip on sights like Russia Egypt Poland and East Germany. Polish had holes drilled in rear sight leaf inorder to hold 2 and 1 was used in front clip on sight. They worked real well esp when you used a different color in the rear which doesn't wash out the front one. Sometimes the rear bringing closer to eye it's brighter. Therefore it sometimes washes out the front sight making it more difficult to put on target and see your target. Ones I used was told to replace jic around 7 years because of going dim. I preferred them a little dim because of washing out target. Blue in rear 🔵🟡🔵 each person. May prefer other combinations.

Very informative and useful information sir. Well done and thank you.

Very interesting. I have a number of tritium watches. I really like them. However, I don’t think they are for everybody. T-100 tubes are never as bright as good lume is, and it needs to be very dark to notice them. The advantage is that they glow continuously without a charge for years.

Great information! You killed it 👏

Thanks a lot for this explanation. I had my eyes on a Carnival tritium T25 from Alieexpress. It really is appealing to me. After your video, i have to reconsider. I stil like the concept of tritium luminous hands on a watch. Let me compliment you on your high quality videos. The are always very useful, no bs here.

Thanks For The Education... Excellent Video.!!

I just purchased my first tritium powered rifle optic and was curious to the science behind it. Very informative video.

Very informative video. Thank you for making it!

Shane I know I'm late to this party. Thank you for doing this video. I have a Marathon Pilot's Navigator on the way so I was curious about how tritium lume works. Thank you for paying attention in school 😂✌🏽 I love your channel bro.

That's brilliant info sir 👍 thanks I feel very informed now.

Extremely informative thanks learnt something today😉👍

Damn, this was explained so thoroughly. Awesome. Subscribed.

Perfectly done video, well done :)

Thank you for the insight; I have a 1968 Tudor Submariner with tritium dial & I had to shine a flashlight for a long time to get it to lume. Now that I know most likely it’s somewhere close to 1/16 life at this point then that makes sense. I will just enjoy it for what it is & not try to ruin it by refreshing the lume. 😊

Incredible information, thank you!

Great, informative video. Thanks!

Vary interesting and informative Thank You 👍👍

great video, thank you for explaining tritium tubes. i agree with others that lume is so much brighter than tritium tubes..

This is amazing and I learned so much! Thanks

Great video! Thanks. Do you happen to know what the ‘original’ color of the tritium watch indices/hour markers was, say on a Speedmaster? Was it white or tan/creame?

I learned a lot. Please tell me where I can find T-100 tritium viles to replace night sites or use in jewellery?

Very informative video. Good job.

yet another excellent video, Cheers 👍👍

Good information. Thank you for sharing your knowledge!

Awesome info, and very well explained 👍

Smart intro. Important matter to review on contemporary watchmaking. Thanks for sharing your view. Regards.

Well done and easy to follow.

Great explanation!

Very useful information man. Gun knowledge, science, and watches, a true man of culture.

Wow. What a fantastic explanation. Thank you very much!

Great video.And good explanation.

Fascinating and excuse me, illuminating! Thank you.

Many thanks for this interesting video. Could you make another one about Super Luminova 3, please? Many thanks

excellent video. many thanks

So a T25 can last a whole military carreer. By the time it go dim you will be sitting into an office. Really informative video, thank you. I'm reassured that my Marathon watch will be fit for duty!

I have one of those 'Nite' watches that you showed on your video, they are made in my hometown of Christchurch, England. The tritium lume is excellent, whilst not as bright as a Seiko dive watch after being charged, it will outshine it after about 15 minutes.

Thanks for the video.This info is greatly appreciated.

Very interesting....thanks really learned something new...

Thank you for the explanation! Btw, where do I buy the tritium fobs from your images?

excellent video as always. we used tritium in the scopes on our rifles and in compasses in the Marine Corps. i'm not sure if this is true, but according to classes we get, tritium becomes 10000x more hazardous if exposed to flame and is then considered dangerous.

Great explanation on tritium thanks for doing this video!
