I had a chance to look at this exact variant yesterday in one store and then take a close look at its 2nd cousin, the 5711/1a. My personal preference is hands down for the RO. It's visually more interesting and has more subtle points to the case and bracelet finishing. The movement is also more highly decorated and worth more than a second glance. Confirms my decision as to what to get next. But you really can't go wrong with either.
