Rolex President - 18038 or 18238???

[sennheiserz]

I'm hoping some of you good folks will weigh in as I have a few questions.

I am within hours/days of pulling the trigger on one of these. I originally thought I'd get a YG Oysterquartz and tried it on and really liked it, but for the same price I can get a 18038 and for a little more I can get the 18238. I think I'd rather stick with automatics as I have sensitive hearing so I'm worried the Oysterquartz tick will drive me nuts and I like the proper president bracelet more.

Question 1: Between the 18038 and 18238, I know the 238 has the double quick set, but is the bracelet any different? Is the case?

Question 2: Is there a weight or center link difference between the 18038 and 18238? I am paranoid about bracelet stretch.

Question 3: Is it totally worth the extra few $k to get a decade newer 238?

I'm leaning heavily towards really going for it with the 18238 but any other info to support that decision will make my choice a lot easier :)

Thanks!
