Rolex GMT for graduation present in 1969 (they ran about $350 at the time). Stolen in 1983. Replaced in 1985 with a two-tone GMT with rootbeer bezel and dial. I wear it every day, hack it about once every couple months, and for off and on DST. It's currently within a second of these folks time:

Every now and then I look at a Breitling ... but why?
