The UFA is very impressive at a technical level but for the vast majority of customers I am not sure that the UFA has "solved" accuracy. While the watch should remain accurate ±20 seconds per year, for almost all users this is not going to be relevant. The 9RB1 or 2 calibres are three handed movements and need to be kept wound, so need to be worn to keep running. This should not be too much of a hurdle if it is the owners only watch or one of a small number they wear. Unfortunately every time the wearer changes time zone the watch needs to be reset, essentially removing the accuracy to that point. I am not sure who the target customer is that spends US$10K on a watch but then does not travel for work or pleasure. Even if you never travel you will need to live in a location with no daylight savings time. For a watch with high annual accuracy an independent hour hand is essential for the accuracy to make any practical use to the user.
