I'm a big watch collector. I tend to collect the slightly more unusual end of the range, either they are leaders for their time (I have one of the first ever Casio Pro-Trek watches that combined thermometer, barometric pressure and compass) or just particularly odd.
There's a good list of the Top 10 Geek Watches available this morning that may be of interest to those readers who want something that makes them look the geek - at least to the people who recognize such things in the first place.
Of those in the list, I don't have any (although I'm just about to purchase a Suunto X9i to go with the X6HR I already have), but then I'm also surprised that the Fossil Asteroids watch, one of which I purchased in New York last year, is not in the list.
