Thanks, man!

🤣🤣🤣 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 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.

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...

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

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.

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.
