not sure the tritium dial is key, on the contrary I tend to prefer the Luminova dial. I'll explain why as it might sound surprising for a vintage fan like me.
A real vintage Type XX is definitely great, especially if military background and even better with corresponding documentation.
But the 3800 is the modern version anyhow, so for me I either go for the real vintage (military) version, or for the modern version i.e. Luminova markings.
At least that's the choice that I had made and I have never regretted.
My 2 cents...
