as displayed in "docbchan's" e-mail above. In fact, I sold the very same AP in that e-mail and then purchased the 5711. I found the AP RO to be rather uncomfortable while the 5711 to the contrary is quite comfortable. It doesn't matter how beautiful a watch is if it isn't a pleasure to wear.
I may be in the minority here, but I prefer the clean lines and balance of the 5711 to the asymmetrical complications of the 5712. I had had the opportunity to acquire a 5712 instead of the 5711 but turned it down for that very reason. The 5711 is elegant and understated, demonstrating the notion that less is sometimes more. The case and bracelet of the 5711 appear to me as one seamless design; the 5712 less so. Some people who have responded to your e-mail find the entire Nautilus line to be "ugly," irrespective of the model. While I certainly do not share that view, these differences of opinion reveal very simply that beauty is in the eye of the beholder, as the adage goes.
The one drawback of the 5711/1A with which I do concur is that it is not really a "sports" watch. If you want to wrestle with alligators, buy a Rolex. If you want to have an elegant steel watch that you can wear with a sportshirt and trousers or even a suit, then the 5711/1A is worth considering. Those were my considerations before purchasing the Nautilus, and I am very happy with my choice. And, although the PP movements speak for themselves, I should note that it keeps perfect time.
Good luck. The journey is half the fun.
