If I may, I'd like to add on the IWC Ingenieur ref 3227. Not strictly a "dive watch" but a good option in the rugged style you like.
Here's a link to one that's NOS: http://www.chrono24.com/en/iwc/ingenieur--automatic-amg--id2371374.htm?dosearch=true&goal_didYouMean=1&query=iwc+ingenieur+322701&dosearch=true&urlSubpath=/search/index.htm
Stitch and i were talking about this watch yesterday...cant believe i forgot to suggest that. The ingy is an awesome watch. Rugged as hell too. I love the bracelet, but it also looks awesome on a strap..IIRC they did an AMG version on a black kevlar strap that was really sporty looking. Not something i typically like at all but it really looked nice on that.
