Depends on how you take care of it. The Don Ramon lies flat on your wrist, so the caseback is where the wear is. I would think that you can coat the case back with a thin layer of acrylic or similar so that the plating would not come into contact with your skin. On the Montoya, which I also have, the main point of contact is the largely the crystal portion of the case back (although the crown probably gets a decent amount of wear from having to set it all the time), and would probably last longer just for that reason. I think that of the two, I like my Montoya "more" than my Don Ramon and it gets more wrist time, but they are both beautiful, as Sardonix's pictures accurately show!
