The RM is smaller but the lug to lug is still quite long. It wears bigger than some other 38mm pieces. Ironically, the Speedy Pro wears smaller than other 42mm pieces so while there is a difference it may not be as big as the figures suggest. Maybe try before you buy. I love the RM, it is very low profile as the curve of the bezel continues into the crystal so it is slim for for an auto. I have both and have no problem with either, but my wrist is slightly larger at circa 7.2" so my experience may not be all that useful.
