Have only had it for a few days. Love it. Dresses down, dresses up. So far extremely accurate--keeping up with my smart phone. Comfortable to wear. Rare model--there are none in the US with waiting list. Tiffany told me they have a waiting list for it of over 30 people. I was first on the list, supposedly, of another AD, but have been first for more than 2 years. Bought it at Patek Salon. They didn't even have any on display. Had to ask for it and brought the only one they had, supposedly, from the back. They were inequivocal that they wouldn't be selling it if all early issues had not been resolved. Anyway, love the watch. Joining my other three pateks, 5117, 5149 and 5146. The one thing I am still getting used to is reading the time, but I am starting to get it.
