Do you you all realize that tritium is radioactive? It's the radioactivity that is driving the glow in this watch.

Johlarsyou should look up the difference between alpha, beta and gamma radiation.
I'm more concerned about plastics in the environment, and the rampant use of petrochemical fertilizer and pesticides. I swear cancer didn't use to be so prevalent.
An now I know way too many people who have cancer or passed away from it.

Good price. But Not-so-brite. https://youtu.be/2hTGLEfjmUY?t=7m54s (jump to 7:54 for lume comparison)

PeekPokeObviously you did not pay attention to what the reviewer said about how Tritium works.
This comparison is like apples to oranges. Sure, the Seiko Monster looks great but it will wear off.
If you have a watch with any kind of luminescent paint, you need to "charge it" with light. Like the guy did in the video.
Furthermore, if you would keep said watch in the dark for a week, you would not be able to tell the time as there would be no lume "left" whatsoever: it wears off. The watch with tritium however, would be as clear as before.

NishikantaYou must be new to watch collecting, so let me enlighten you. First off, tritium tubes don't come cheap especially brighter ones and this watch comes with over a dozen of them. Secondly, this isn't using some garbage quartz movement you'd find inside of some $10 throw-away Walmart watch, there are actually different grades of quartz movements, some of which can come in watches costing well over 10 times this watch. There are also crappy mechanical movements too costing a fraction the price of a quality quartz movement, you can definitely get an auto movement in this watch and at this price point with all the above mentioned features, but who says it'll be any good? Lastly, it's AR sapphire, which, again, isn't cheap. FYI quartz watches can range from $10 to over several grand depending on what additional technology is inside it and yes the price is entirely justifiable. There are high accuracy quartz watches out there with temperature control that increases accuracy and their accuracy is an issue to hardcore watch collectors, even if that means being a few seconds more accurate a week which can add up. I recommend doing a little more research on what different type of quartz watches are out there before thinking that one can't be worth it's price.

Thedonn007Can deal with the date, at least it doesn't have a cyclops. But that logo is a crime against god and man.

It isn't necessarily true that a T100 is 4 times brighter than a T25. It's not even likely.
A T25 has up to 25 mCi of tritium, and a T100 has more than 25 and less than 100. So first, a T100 could have only 26 mCi and still be properly designated a T100. Second, this isn't a measure of brightness but of the total amount of tritium contained at ship time. I have one T25 tritium watch with only 6 tubes (at 12, 3, 6 and 9 o'clock + minutes and seconds). If it's loaded with 25 mCi, that's around 4.17 mCi/tube. This Isobrite has 23 tubes, and if it had 26 mCi that's only 1.13 mCi/tube. Then again, 100 mCi would mean 4.35 mCi/tube. All else being equal, this watch should be about 4.3% brighter than my other watch.
Assuming equally good phosphors (likely, since the manufacturer is likely the same; there are only a couple sources) and similarly-shaped and oriented tubes, this analysis should be reasonably accurate.
Where you're really going to get a brighter and longer-lasting tube isn't by adding more tubes. It's by having more tritium in the same number of tubes. I understand that getting into these specifics might make for dense marketing, though -- look at this post!
All that said, the watch looks pretty good to me at the price. I have a Ball T25 watch I usually sleep with but it's hard keeping automatics wound right when you wear them all night. I think this quartz will be a good solve for me, and I've joined the drop.
TL;DR: T100 doesn't mean the watch is brighter or that it will last longer. It can just mean 4x more equally-bright markers.

Correct me if I am wrong but I believe the reason for the H3 T100 standard is that it is the most you can have in a watch.

Even though T100 does indeed mean 26mCi to 100 mCi, we always use as close to 100mCi as possible. We really do love making our T100 watches as bright as possible. T100 also has a lot of country-specific restrictions compared to T25 being allowed to be sold in almost every country (except France). Therefore, if we're already going to limit our potential markets by making a T100 watch, we believe in making it the best possible T100 watch. We have a lot of new T100 models in the works that will surely impress!

I'm hesitant in ordering one, because as usual it's a huge gamble with having to pay additional import fees and taxes here in Europe. Massdrop should facilitate some EU shipping center, because whenever stuff is shipped from within the EU you only pay for shipping. It's really annoying that any potential 'good deal' is killed by this... I had to pay a lot extra (in total 24% on top) for my Armourlite pocket watch :-(

We'll discuss this idea with Massdrop and see if this is possible. The problem is that as a US-based company, Massdrop would need to bring the products into the EU and pay the import taxes as soon as the products enter the EU. That would drive up the cost of the product. The customer would end up paying the tax in the end, one way or another.

ArmourLiteThat's a fair point: I totally understand someone needs to pay. Point taken. I think I was to much focused on my own pocket. Thanks for clarifying! Much appreciated.

Finally jumped on this one after months of deliberation. I have another Armourlite that I wear frequently. Not bothered about the quartz - in fact, my quartz watches tend to keep better time better my automatics. Overall a sharp looking watch, looking forward to it.

Ummm... duh? No one buys an automatic because it is more accurate.

This seems like a pretty darn good deal, I'm not an expert, but you can get Chinese Yelang watches, pretty well made, and to get T100 they are around $230, but they have far less, smaller Tritium markers than this watch, just really short indice markers and certainly not numbers made up of tritium sticks, oh but they are automatics, even so though, this seems a really good deal for a T100 watch, and especially with a SS bracelet, leather and a NATO? Nice one, I've been pretty critical of drops lately, thank you Massdrop and thank you Armourlite!

I believe the term was actually designed to convey an outer bound on the amount of radioactive material. There, too, it's a pretty wide variance.
I don't dispute that your watches containing between 25 and 100 mCi are visibly brighter than those you've seen with <25 mCi. I also don't dispute -- though I don't yet know -- that the offered watch (which I have purchased and look forward to receiving) is brighter than many, most or all T25's. My point is simply that T100 is not, in and of itself, a promise of either brighter or longer-lasting illumination.
I'll look forward to comparing it to my T25 Ball and Smith & Wesson watches for brightness. If I remember, I'll also update in 25 years regarding glow longevity. :)

There's certainly some variability. I have a T25 Ball watch and both I and my 83 year old dad were able to see the illuminated markers with unadjusted eyes, just walking into a shaded hallway in the evening and turning off the light.
Not all T25's are equal, I guess!

anyone an idea if it is possible to remove that toothpaste logo from the dial?
