Hi! Our 25th is coming up. My husband has talked about owning a Patek Phillip Calatrava for as long as I can remember. We looked at them in person only once at a jeweler in St. Thomas. It was have been around 2005. The watch he loved had a hobnail bezel in rose gold with black alligator strap. I believe the "inner workings" could be seen from the back of the case. In looking at various sites, it looks like it might have been a 3919 or a 5119. Frankly, I have no idea what I'm talking about. Just trying to figure out what to buy. And- new vs pre-owned. Looks to me like the new version is much less formal. Any direction from those of you who know??? And, if you have a sense of pricing that is fair, that would be great too! thanks so much. Cindy
