Any long distance runner's w/a Rolex

[Tudor66]

Ok, don't shoot, I understand that Rolex watches are not designed for running, and moreover I should wear my quartz watches for running, which I currently do.

But, hypothetically speaking, if one were to use a Rolex for long distance running, which one would it be...? I spoke to an AD who indicated that the EXPII 39mm had been designed for serious movement/activity, with special case modifications for said activity. I had always thought that the EXPII was the same as a GMT MasterII, with a different bezel feature and less shiny case.

I run up to four days a week, 1 to 3 hours at a time, and yes, I'd wish I could wear a beater 16570 polar while I'm hitting the pavement....
