Yes indeed, all dial watches like the 39mm Explorer do wear large, so I think slightly smaller at 38mm would do a world of good. It's surprising how much of a difference just 1mm can make, but it can. Apart from the size (I'd still get the new 39mm version if I could, though, but I would prefer it at 38mm), the new Explorer looks just about perfect to me in every other way.
Thanks for the video links, @RFX45.
I love the size of the 39mm Explorer. Does probably wear more like a 40 but relatively thin so it works well on the wrist.
On a related note, always a little weary of re-sizing. I agree it can make a huge difference, but sometimes not in a good way - even 1mm might throw off the balance of dial/watch. E.g. Daydate 40 vs Daydate II
