Constructive feedback - It would've been useful to see a timelapse to see how the lume fades over time compared to the Seiko, and to see how long it takes until the lume matches the brightness of tritium

I still much prefer tritium. It glows 24 7 for 15 to 25 years. I drive a truck at night and there is absolutely no lume that will stay bright from sun down to sun up. I wear my Ball watch almost exclusively because of that. Ball is my favorite company, but the tritium is the reason I wear it so often. When using tritium you must look at what tritium is being used. T100 tritium tubes are the brightest. T25s unfortunately are what many brands use because it's half the cost. Please, please, please put tritium in your Islanders! I know I've been asking for a few years now, but I love the Calabro GMT and the Brookville. I own them and wear them, but the tritium would keep them on my wrist all night! Anyway, thanks again Mark. God bless

Not giving up my tritium for anything with passive luminescence. I've had both, and tritium is better for my purposes (lots of nighttime ops).

If I put my Seiko with my GSAR next to my bed, and wake up at 4:00 am and look at them, the tritium tubes are brighter, I’d love to do that test with Mariglo

Love the lume comparison, helps me understand what I'm looking at.

Nice tactical watch. Love that black vs white contrast. Seems to be a “peace-of-mind” type of watch i.e. put it and forget it, regardless of the activity you do in one day. AND, me being from Canada, I feel proud that they are built here in my neck of the woods. Thanks for sharing Marc.

I have several Deep Blues with T100 tritium and I have to keep them covered when not on wrist or they light up the room at night. Granted, there are 4 of them, but they are all legible throughout the night, even in Alaska. Whatever Steeldive uses is incredibly good as well, just received one and was impressed.

Thanks 4 update on new Maraglo

As others stated, you really needed a shot of the watches after they'd all been in the dark for 8 hours. As someone who works at night, Tritium is great in practical use during the night. Again, as a few others have said, I'm also waiting for an Islander with trit tubes, preferably blue (BGW9 is such a pleasant lume color that you also don't use enough of in your normally lumed pieces) or orange. Several of your designs lend themselves to it, with wide markers and hands that could fit the brighter T100 tubes. That said, even T25 is perfectly visible at night, when your eyes are already adjusted to the dark.

Just bought the SSDNAV and love it ! Traded my JSAR for it. Couldn’t be happier. It’s gained half a second in almost 2 months.

Way more interested in that GMT teaser you snuck in there! Looking forward to those!!

Marathon watches are nice but you can get a Deep Blue with NH35 movement, similar case, 200m wr, Tritium T-100, sapphire crystal with AR coating, nylon strap for $179. Just sayin 🤷🏻‍♂️ Thanks for sharing them Marc. Have a great day.

When you said you were releasing a 9075 gmt soon I was hoping and hoping it would be the port jeff but redone. I never thought you would actually do it. Buying that immediately!

Looks like the same nylon strap and tunnel keeper as on my cheap Bertucci. Super comfy. No giant rings to bite into my wrist.

Love me a battery hatch - the Swatches I owned in the 80's and 90's had them and it meant I could easily change my own batteries by just unscrewing the hatch with a 2p coin (which fit perfectly!) - no need for any special tools or a trip to the jewellers to get the back off (and many a good watch was cosmetically ruined by jewellers being too clumsy with the tools). If the Tissot PRX quartz used these I'd have probably bought one - but sadly it has one of those awful snap on case backs that are almost impossible to remove without marking them.

I'm just here to say again that a Island watch line of aftermarket Marathon bracelets for the GSAR/TSAR would be amazing.

T25 requires your eyes to adjust to the dark, but T100 is pretty visible. It's too bad Marathon's tritium offerings don't use that.

Myota gmt, you tease. I cant wait Mark. ❤

Excited about the port Jeff GMT

Port Jeff true traveler GMT is what ive been waiting to hear

I'm skeptical this new maraglo is going to beat tritium tubes after several hours. Once you go with tritium it's hard to opt for anything else.

I initial glow of the Maraglo blows the Tritium away but in the middle of the night the Tritium blows the Maraglo away. Given the choice between the two I would go Tritium every time. 😊

If they release a GSAR w maraglo It will be a blockbuster

Thanks.

Did you say you had the tritium one covered or did it just not glow at all?

Awesome stuff Marc! Is the maraglo similar to what Lume-tec uses? My Lume-tec glows as the light dims and lasts all night.

Not sure I understand: Is "Maraglo" actually chemically different, or is it the same substance as other Swiss / Japanese lumes and they're just using the term to brand / market their "better" application of it?

I guess if you're were a desk-benched military enthusiast, the Maraglo would be good for you. However, if you're in the military, Marathon purposely used H3 and not H10 tritium so that the soldier can see the time in the dark, but give away his or her position under combat!

battery life? question is it possible to find different types of options for battery e.g.(5-10yr not just 2-3yr)

These aren't really for me, BUT I am very interested about the Port Jefferson coming back as a Miyota 9075 based GMT. I expect that it will have a 24 hour bezel. Will the colourways be the same or will you me reworking those? I like the idea of an affordable trevellers GMT. There are a few around with the 9075 movement...

yo mark could you please give exact wrist size when you do your demo tks...

It looks pretty nice, except for that tiny (unreadable for me) date. If there were a no-date version, or one with a larger date, I would certainly be interested.

Ball has amazing tritium tubes, but since the started using in house movements, the price has gone through the roof and out of my range now. Really nice watches IMHO.

Fresh tritium tubes are nice. But I have several Marathons with dim or dead tritium tubes after several years. I should send them in for replacement dial+hands. Meanwhile, the Maraglo models are going strong....

Bummed to see the tritium gone, i love mine.

I am still on the fence re: Marathon. It is the perfect premier field diver. But then I keep looking at Sinn 857 & cannot decide!

It would've been a good opportunity to make the body thinner. Now that there are not tritium pips, it would've been nice to see a 11mm thick body like on the steel version. 😢

Sticking with my Bertucci

My GSAR is mostly Tritium lit and only has MaraGlo on the bezel pip and it's as good if not better than Seiko LumiBrite.

Will you be adding Ball watches to your site?

Has Marathon hinted at replacing the tritium tubes in future GSAR’s or other watches?

How is that mil. Spec. With a push/pull crown? Maybe in 1986 but that is just wrong.

I dunno about marathon, but my Luminox is bright enough to read by, and it's just a basic 3000 series model. I wouldn't want it to be any brighter, or it would become a nuisance in a dark room.

My sleeping watch😄😄

will they be adding it to all of their pieces/

Tritium glows with the same brightness for 15 years or more. Comparing Tritium to light activated luminous paint is a completely spurious exercise since no light activated luminous substance can compete with Tritium tubes after a couple of hours of darkness. That is just basic physics and the chemistry of how luminous substances work.

try a deep blue with Tritium 100 tubes. the tritum is bright enough to see in the day light

I accidentally dropped my navigator on the floor once. Back popped off, movement popped out, hands popped off. Not really mil spec

It’s cool, but still way overpriced for what it is. If it had a high grade titanium case I could understand the high price. Fibershell can’t be THAT expensive to produce.

🥇

i really like the white port jeff too bad it's discontinued and adding a gmt on a new would make it pricier 😢.

Where was the blow away?

For a quartz watch with only 50m wr and a non colour matched date this is too expensive.

I couldn't even see the tritium on my lappie monitor.

Was that Tritium tube a T25 or a T100? It does matter. Tritium all they way! In person is what matters, not what is perceived through a camera that can't capture what an eye actually sees.

I think you're just playing with the distortion of the camera, the recording process, and displaying the recording result on computer/phone screens. My eyes (-4.5, wearing glasses) can easily read the Tritium dial at dark night.

60mm of water resistance is more than the average depth that watch lovers expose their watches to.

The bezel on these is terrible. It turns awfully, and within the first week mine chipped. A month after getting it replaced, it popped off. Meanwhile i have a luminox ive kicked the hell out of for 6 years and it’s just missing a little paint.

I have never seen any passive lume watch (including Seikos) that was worth sh#t after a couple of hours. Marathon just figured out a way to make it cheaper.

Maraglow may last, but the amount used on the hour markers is too little. I thought it was superluminova vs trit in the comparison. It just looked meh. T100 trit FLAT tubes is the way to go.

That must be old tritium yo.

Tritium has a halflife of 12.3 years. So, you're on the clock with how long it lasts.

Great stuff tritium. Until the half life. This is partly what got me into this stupid hobby in the first place. Tritium's half life on my old Luminox.

If your claim is to say maraglo blows away tritium, why would you cover the tritium? Let the potential buyer decide by showing them side by side.

This video is fairly inaccurate. Yes, initially, painted lume like C3 or Seiko’s Lumi Bright is much brighter than tritium tubes, but it rarely lasts all night, and fades extremely quickly, needing to be charged again. I have the SSNAV from Marathon, and I can see the tritium extremely well in a dark room at night as soon as the lights are out, and even in a dimly lit hallway it’s visible that the markers are glowing. Your video exposure is adjusted to show the painted lume as “normal” at the outset of its glow phase, which makes the tritium appear as if it’s not glowing at all, but if you were to show it as the naked eye sees it, the tritium would be far more visible than you’re giving it credit for, even alongside these other painted lume surfaces. If you showed the same side-by-side, say, 7 hours later, the tritium would likely be far brighter than either of the painted markers. Watch reviewers love to shine a light on a watch and go, “OOOH! Look how bright!” But they often fail to mention that it only lasts a minute or two before it drops to a dim glow, and then within a couple of hours is almost unusable. Tritium has a constant glow until its half life kicks in and it dwindles, but that’s over years, not minutes or hours.

man I agree anything any good not made in chitown is too $$$$.... the chitowners are laughing at us as usual

How much for SKX? Just kidding! LOL

Zeroth

Tritium only needs about 45 minutes (at most) and it'll be brighter than any lume watch! The real question is, how will tritium compare to lume 10-15 years down the track? I love tritium, I just fear that it'll be basically useless long term. I highly doubt that the tubes could be or will be replaced.

They removed the tritium and I can no longer coordinate the watch w/ the night sights on my Glocks 😢

This of course presumes you expose your lumed watch to direct sunlight for an extended period of time. My Marathon MSAR (circa 2010) and my Ball Marvelight are far superior to any lumed watch.

So are all Marathon watches grossly overpriced or what?

with that background, this is the closest well get to a marc and flossy cross over. white shoes...CALM DOWN.

I’ve always liked this watch, but it is simply overpriced for a plastic and quartz piece. All the more so with the cheap tritium. Hmmm…what if Islander did its own take on the Marathon Navigator?

show the gsar for comparison.

Mmmm?

What Maraglow 😅😅 Who do try to kid? Marathon is gone

Boring

Does this Mariglow version lose its DOD status? is that why it won’t bear US Govt mark? Thanks Marc

Marathon are one of the best watches out there Mark,I’ve used them for many years and trust them 100% ,good luck Mark the guys who know what they are talking about will snap them up ,thanks.📐👍🏴󠁧󠁢󠁳󠁣󠁴󠁿🛩️
