Marathon TSAR hydro mod

Do you remove the second hand to make the battery last longer? I've heard that hydro mods can negatively affect battery life.

I love my marathon MSAR, for a military spec watch why remove the seconds hand though? I feel like that tritium tube tipped seconds hand is one of the coolest parts of marathons no nonsense aesthetic

Wow this is interesting, what does having the oil do, I’ve never heard of this? Is that why the dial doesn’t have the usual deep look?

it would give a different look on the dial, just like a lcd screen. there are some watch manufacture that produced oil filled watch just like ressence .

Makes the dial appear to be up against the glass. Improves Water Resistancy up to as much as 10 times apparently because no air inside the watch to be compressed. Drastically improves viewing angle as cancels out the glass glare & finally allows you to tell the time under water without having to be looking at the watch flat & directly in front of your face for this reason most hydromods are done on Dive Watches to increase functionality. #modding #diver P.S. should only be done on Quartz Movements though

No bubbles! This may be the first time I've seen this done to a watch that was worth more than a cell phone bill.

I think it looks super cool!

Okay after reading the comments I understand why now

I will do my best Nancy Kerrigan impression. Why.....why.....why? I wear a TSAR every night in bed because of the glow in the dark tubes and i cant imagine experimenting with a watch like that. As far as water proof goes, I think if the watch breaks or floods you got worse problems than what time it is. Good job pulling it off at least. Duane Black Diamond, WA, 98010

I remove it for several reasons:

1. I don't like the 60 ticks per minute

2. The color of the tip was crimson as opposed to the dial print which is bordeaux..

1. Yes, it saves some battery life as the second hand will not have to plough through the oil.

I agree. However, the tip of the TSAR's second hand is does not feature a tritium vial but a regular Maraglow lume. I don't need it to time seconds, that's why I took off.

Yes, it removes the topography of the dial, at least when you look at it from an acute angle.

Hi Duane, I do the same. I have been wearing my GSAR at nighttime so far. I also own a Sinn Hydro and I always felt that it would be overwhelmingly awesome to combine these two technologies that Marathon and Sinn offer. I have it now! But I have to admit that I was super nervous to screw down the caseback of my Marathon TSAR. I was afraid that too much pressure within the case might make the tritium vials implode. I was lucky they did not implode. I opened the case back again after I had been successful to put some expanded polystyrene balls between the movement and the caseback. They operate like buffera and the air within gets compressed when you close the back or when the watch gets heated up.

Haha, Nancy Kerrigan! At least I didn't beat my watch with a steel rod...

Thanks Wayne, I agree with everything you said except for the reduction of glass glare. On my Sinn Hydro there is still significant glare. That's why I also swapped the Marathon original sapphire crystal with a double AR aftermarket sapphire crystal. The dial looks very black now. It's like looking into the night sky in the Atacama desert in an altitude of 9,000 ft.

🤣🤣🤣 Exactly, I was very nervous to to that! But I figured if Sinn can oil-fill watches then I can do it as well. It really is no rocket science. It really is fun. But it also leaves a great mess. It was definitely worth it. And yes, I managed to evacuate all the air within the case. I was mainly able to do that with expanded polystyrene balls in behind the movement. When the watch cools down outside in the winter the oil compresses to its minimum density. That's when the air bubbles expand. If you add balls of expanded polystyrene, the air will be trapped in this material and not flow freely underneath the crystal.

Thanks, man!

Oil-filling technology keeps advancing. I'd never heard of this styrofoam trick. It seems to work.
