Wow, what a nice looking piece of gear.

Maybe we're all jaded by modern gear using state-of-the-art manufacturing techniques.  "Vintage" gear and gear with overly complicated mechanisms sure do look a lot nicer than I remember them looking when I was a kid.

Perhaps a reason why Rolex sells so many watches at 100x the cost of a Casio (which keeps better time, has more features, and will still be ticking after sitting on the nightstand for a month).
