I think this is a bit of an extravaganza when it comes to watches and fountain pens. Both the watch and the fountain pen are hard to get as they are not in production anymore (Seiko actually announced that they will reissue the watch)
I am talking about the Seiko Alien watch worn by Ripley in the Aliens movie, designed by Giugiaro.
In my mind, I immediately thought maybe there is an equally interesting fountain pen designed by Giugiaro.
After a little research on the internet, I found out that Giugiaro actually worked with 3 stationary companies. The companies are Aurora (Italian company based in Torino), Parker and Sylvapen. Not much information is about what products made by these companies were his design. I wasn't happy with this answer so I looked for the fountain pen some were else.
The watch has a bold design, is a chronograph what makes a lot of sense based on the fact Giugiaro is known especially for his car designs. The dial and subdials have a feeling that they were taken out of a car. And the bold colors combined with the sterile silver case make it unique. Not to mention the buttons on the side...
I think the best bet for a fountain pen to go with the Alien watch is Rotring 600.
It matches the simple and unique style of the watch. Sharp corners on the barrel and cap with knurled elements on the grip, cap and barrel end. A nice hint of yellow on the cap and nice golden nib and the traditional Rotring ring and the writing in red.
It looks very much like a tool but at the same time is a thing of beauty and I could say a cult has been formed around these beautiful instruments.
If you have other suggestions please let me know in the comments. You can add pictures as well.
