Is there anything more technologically ironic than the holy holy holy union of a mechanical watch and a fountain pen? Who cares, Richard Mille's new S05 Mechanical Fountain Pen is every kind of awesome and one other kind of awesome that hasn't been invented yet. Remove the cap, press the button on the end, and the so-called recoil escapement pushes the white gold nib out of the front of the pen.

Recoil escapement. Can't just throw that term out without explaining it, so here: A recoil escapement is a series of interconnected levers, gears, and springs that stores energy with the intention of releasing it in a pushing or striking motion. In the watch world, you'll most often see it used in minute repeaters, watches that will chime the time when you hit a button. Safe to say this is the only fountain pen that uses it. You "reload" the pen when you put the cap back on—transferring mechanical energy back into the escapement.

After all that wizardry, it's easy to overlook the pen's exterior, which itself is pretty cool: it's NPTP carbon, the same material used in the sails of racing yachts.
