Because some people have so much money they can spend more on a writing pen than most people make in a year, this is the $105,000 Richard Mille RMS05 Fountain Pen. I bet it doesn't even give good handjobs.
According to Richard Mille, it took the Swiss watchmaking company four years to develop the RMS05, which incorporates a mechanical movement on par with an RM watch calibre. The Grade 5 titanium, 12-jewel movement sits inside a barrel of NTPT (North Thin Ply Technology) carbon, which is a laminate of thousands of parallel layers measuring less than 30 microns thick. The layers are built up out of resin-impregnated carbon fibers that are woven on a special machine that modifies the direction of the weft between layers by 45°, then heated to 120° C (248° F) at a pressure of 6 bars to create a distinct pattern before moving on to a CNC machine for forming.
It extends the hand-polished 18K white-gold nib automatically from the barrel at the press of a button. That may seem simple in a world of retractable ballpoints, but Mille wanted the action to be smooth and precise, and hence the mechanism, which is regulated by a recoil-type escapement to keep the speed of extension under control.
Aaaaah, so it has a mechanism to regulate the speed of the tip's extension. That is very important to me, I can't have my pen tip extending all willy-nilly. So, how many of these $105,000 pens do you think the company will even sell? "One?" Exactly -- way too many.
Keep going for several more shots including the complicated nib-extending mechanism, which looks like part of a watch.
Thanks to Max, who prefers his pens the old fashioned way: crayons.
