Would I be able to replace the 0.5mm Mechanical Pencil for a green ink replacement?

I've ordered replacement ink tubes, as well as the pencil tube. They are all the exact same size, so I cannot see why it would not work.

Is it as smooth as the 800

I am not familiar with the 800. But, the pen works great and it feels quite smooth to me. It was a great purchase.

Can it write upside down (is ink pressurized?)

No. The refills are not pressurized, and it won't write upside down (at least not for more than a couple of seconds).

Is this a gravity controlled pen?

I'm not sure but I do know that how you hold the pen facilitates what color you want it to write in. It is pretty unique in that regard and I'm sure gravity some how plays a part with how the positioning of the pen causes the pen to write in the appropriate color(red, black, blue, pencil)

Excellent quality and amazing build

Can’t go wrong with German engineering when it comes to writing equipment. I’ve been using this brand for over 30 years, not only writing but also in architectural drafting. I love this pen, every color writes super smooth and the mechanical pencil works perfectly.
