Hi all. I am looking for a new watch to accompany my speedmaster, and I'm between a 36mm Rolex Explorer and a 39mm IWC Mark XVI. I have always liked the Explorer 1 for its history and understated looks. The IWC is the closest watch to a Big Pilot that I will be able to pull off with 6.75" wrists. Both have excellent symmetry with the date function on the IWC being a plus for me. Both are similar in price and will likely be worn for a few years before trading them up to something more expensive. (Credit Google search for images). Which would you choose and why?
