I purchased first the RO, motivated by many positive reviews as those expressed in this post, as well as the aesthetics of the watch itself, of course. I found the RO bracelet, however, to be the most uncomfortable I have ever worn; it was stiff, and the links would frequently catch the skin on my wrist. The dial, while beautiful and iconic, is rather one dimensional. Consequently, I sold the RO and purchased the 5711/1A and have not regretted my decision for one minute. The bracelet on the 5711 is seamless; its alternating polished and matte links (which, I am told, are more difficult to manufacture than the simply matte RO bracelet) integrate beautifully with the cushioned dial. So much has already been said about the shimmering dial of the 5711 that there is really no more I need add. All I can say is that I get great pleasure each day I wear the 5711; sadly, I was unable to say the same when I owned the RO. Good luck in your continuing quest!
