Porsche Design watches are cool.
I don't remember the brand, but there was some company a while back making watches where part of the watch was actually made from metal from an old 911. Those were very cool.
But, from a more budget friendly point of view I think the GRD watches sold by Pelican are kind of cool.

I think all but one of these are quartz movements.
These are my favorites. I prefer where the 9, 10, 11, and 12 are left off of the dial, and the numerals are located similarly to the numbers on a tach (ie, 1 is ~8 o'clock)
I prefer the redline marker more like my old 3.2L.
Good aesthetics, but I'd prefer the 9-12 to be left off.
rotated is cool, but I'd prefer to have a redline marker.
This one would go nicely with my Boxster
retro is cool, and I think this is the only automatic movement (and is therefore, a bit more expensive)
They have a few others if you follow the link.
